The present dissertation deals with the synthesis, characterization, and in vitro testing of self-ordered molecules forming nanoparticles (micelles/liposomes) with a hydrophobic core and hydrophilic parts of the molecule. The hydrophilic part of the molecule will be functionalized with functional groups affecting the surface charge of the nanoparticle and functional groups actively targeting e.g., tumors. The core of the nanoparticle will contain therapeutic drugs which will be delivered directly into the intracellular compartments. In this work, the low molecular weight agents prepared in this way with different functionalities on the hydrophilic part of the chains will be combined to achieve the best therapeutic effect. The scope of the thesis will be organic synthesis, and physicochemical characterization. The thesis involves the use of animal/human cell lines in performing basic in vitro techniques with which the student will be familiar.

Současná buněčná biologie otevřela nový směr ve výzkumu a vývoji, zaměřeném na ex vivo tvorbu 3D struktur, které velmi blízce napodobují tkáně a orgány živého organismu. I přes schopnost buněk sebeorganizovat se, přispění nebuněčného 3D nosiče je stále považováno za důležité pro zajištění správné morfologie. Slibným přístupem, jak zajistit správnou pozici buněk pro jejich další vývoj je 3D biotisk. Pokročilým konceptem je pak tzv. 4D biotisk, definovaný schopností biomateriálu odpovídat na různé signály i po jeho vytisknutí. Hlavní limitací těchto přístupů je suboptimální chemické složení biomateriálů, které nedává dostatečnou flexibilitu v mechanických vlastnostech, vnitřní geometrii, schopnosti vázat a uvolňovat biomimetické ligandy atd. Disertační práce bude zaměřena na přípravu a charakterizaci plně syntetických (xeno-free) vysoce flexibilních polymerních biomateriálů na bázi syntetických polyaminokyselin. Pro 3D tisk hydrogelu, bude vytvořen síťovací protokol, který zajistí rychlé utvoření hydrogelové sítě schopné mechanicky ochránit buňky v průběhu tisku a podpoří jejich retenci a životaschopnost během regenerace tkáně. Hydrogely budou modifikovány peptidovými ligandy s cílem podpořit specifické interakce s buňkami. Student by měl mít zkušenosti v oboru makromolekulární nebo organické chemie a měl by být ochoten rozvíjet své znalosti i v biochemických a biologických disciplínách. Při studiu fyzikálně-chemických vlastností připravených polymerů a hydrogelů si student osvojí řadu technik a metod s využitím moderních přístrojů.

Antibacterial surfaces are increasingly important for reducing microbial contamination and infection risks in healthcare, food processing, and related industries. With the growing challenge of antimicrobial resistance and persistent surface contamination, there is a strong demand for durable, biocompatible, and environmentally safe antibacterial coatings. Current technologies include passive surfaces that prevent adhesion and active surfaces that kill microbes on contact, though achieving long-lasting, biocompatible, and environmentally safe performance remains a challenge. This PhD project focuses on the development of advanced polycation-based polyelectrolyte antibacterial surfaces using the layer-by-layer (LbL) assembly technique, which enables precise control over film thickness, composition, and functionality. The project will investigate various types of positive charges in polycation layers and their influence on film structure, stability, and antibacterial performance. In addition, the integration of biologically active agents such as enzymes and antimicrobial peptides into LbL films will be explore to create the coatings with long-term, synergistic anti-adhesive and active antibacterial functionality.

The fundamental challenge is physical realization of low-density 3D auxetic metamaterials with unique architecture and programmed deformation behavior. The research on hierarchical auxetics is in its infancy, it predominantly consists in prediction of their performance using sophisticated modeling and preparation of some macroscopic model structures. In spite of their very limited occurrence in natural materials, the several known examples confirm their advantages. In the systems considered, local mechano-mutability by spatially arranging multi-material unit cells should lead to substantial affecting of spatial profile of Poisson’s ratio, moduli of elasticity, toughness, control of acoustic damping, etc. Important tool will be targeted synthesis of auxetic unit cells and related functional nanocomposites based on both natural and synthetic constituents also including 3D printing techniques.

In biomedical applications, the release of growth factors (proteins) promoting vascularization from biomaterial surfaces is a key factor that supports the integration of biomaterials with the recipient tissue. An effective technique for the preparation of ultrathin coatings is the layer-by-layer technique ("LbL"), which is mainly used in engineering applications. The project aims to develop bioactive LbL films consisting of “charge-shifting” polycations based on poly(dimethylaminoethyl acrylate) (PDMAEA) and the polyanion heparin, which will release the growth factors VEGF and FGF-2 that stimulate vascular cell growth. The gradual change in charge on the PDMAEA polymer will allow tuned decomposition of LbL films and thus controlled release of immobilized growth factors. Doctoral studies will include: 1. Study of the synthesis of PDMAEA and its statistic copolymers by RAFT polymerization, with the aim to obtain polycations with different charge content and hydrolytic stability. 2. Study of the dynamics of film formation and characterization of physicochemical and morphological film properties using advanced instrumental techniques such as surface plasmon resonance (SPR), quartz crystal microbalance (QCM-D), AFM, or CLSM. 3. Preparation of real LbL films using an automated coater for layer deposition and study of in vitro protein release as a function of composition and stability of LbL films. 4. Evaluation of the cytocompatibility of LbL films and the bioactivity of released proteins in collaboration with biologists. The interdisciplinary topic focuses on polymer chemistry and biomedical applications and is suitable for graduates of chemical disciplines, such as macromolecular chemistry, physical chemistry, biochemistry, etc.

Plně alifatické biodegradabilní polyuretany (PUR), nacházejí uplatnění především v environmentálních technologiích jako jsou biofiltry, sorpční materiály, nosiče mikrobiální biomasy v bioreaktorech apod. Avšak u těchto materiálů je požadována určitá stabilita, protože častá výměna/krátká životnost nestálého materiálu není výhodná ekologicky ani ekonomicky. Znalostní mechanismu samovolné degradace v biodegradabilních polyester-etherových PUR materiálech může být předcházeno přidáním účinných přírodních aditiv už během samotné přípravy. Proto tento projekt bude zaměřen nejprve přípravu nových biodegradabilních PUR materiálů s prodlouženou životností. Druhá část výzkumu se bude zabývat porovnáváním vlastností (fyzikálně-mechanické, termální, makroskopické atd.) PUR materiálů s nižší a prodlouženou životností. Třetím bodem této práce bude analýza a monitoring urychleného stárnutí u nově systemizovaných PUR materiálů v abiotických podmínkách (hydrolýza, UV stárnutí atd.). Poslední část se bude sledovat porovnání rychlosti biodegradace u PUR materiálů se sníženou a prodlouženou životností.

Biodegradable polymer systems show numerous technical and biomedical applications. Our team has long-term experience with a reproducible preparation of thermoplastic starch (TPS). TPS is cheap, biocompatible and completely biodegradable polymer. In this project, we aim at the development of TPS/PCL/MD/SiO2/Ag systems, where PCL = polycaprolactone (another biopolymer, added for better mechanical performance), MD = maltodextrin (bio-oligomer, acting as a lubricant that decreases processing temperature), SiO2 = silica nanoparticles (inorganic filler for higher stiffness and barrier properties), and Ag = silver nanoparticles (antibacterial properties). The multicomponent TPS/PCL/MD/SiO2/Ag systems could serve as a bio-material with tunable properties for numerous applications (such as antimicrobial packaging or mulching technology). The project comprises preparation of the above systems (by melt mixing), optimization of their composition and morphology (targeted modification of preparation protocols), characterization of their morphology (electron microscopy, vibrational spectroscopy, XRD), and properties (macro- and micromechanical properties), and participation in biodegradability testing (in collaboration with the University of Zagreb, Croatia).

The long-term success of vascular implants, particularly coronary and neurovascular stents, critically depends on rapid restoration of a functional endothelial layer on their surface. Insufficient or delayed endothelialization substantially increases the risk of thrombosis, inflammation, and restenosis, representing one of the primary clinical challenges associated with current endovascular interventions. The aim of this PhD thesis is to develop a new generation of bioactive, hemocompatible coatings that mimic natural vascular healing processes and provide a unique combination of low thrombogenicity, anti-inflammatory properties, and active stimulation of endothelial growth. The research will focus on fibrin coatings produced through controlled polymerization directly on implant surfaces, which will be subsequently functionalized with sulfated glycosaminoglycans (e.g., heparin, fucoidan, hyaluronic acid) and synthetic peptides promoting wound healing. Fibrin serves as a biomimetic matrix capable of binding, stabilizing, and presenting bioactive molecules in a form similar to that found in the early phases of vascular wound healing. The PhD candidate will optimize fibrin polymerization parameters, tune coating morphology and thickness, and introduce bioactive motifs via specific covalent conjugation strategies, including modern bio-orthogonal click chemistries. The work will involve comprehensive structural and chemical characterization using AFM, SEM, confocal microscopy, FTIR-ATR, and SPR. Coatings will be evaluated using hemocompatibility assays (coagulation activation, platelet and complement activation), anti-inflammatory assessments (macrophage adhesion, M1/M2 polarization, cytokine release), and detailed endothelialization studies. These will include static and dynamic endothelial cell seeding, migration assays, proliferation analyses, and characterization of endothelial markers such as CD31, VE-cadherin, vWF, and eNOS. The expected outcome of the PhD thesis is a fully characterized multifunctional coating that accelerates endothelial regeneration while suppressing thrombosis and inflammation, thereby addressing key limitations of current vascular implant technologies. The candidate will obtain extensive expertise across macromolecular chemistry, surface biofunctionalization, materials characterization, cell–material interactions, hemocompatibility, and advanced microscopy, providing a strong foundation for future research or industrial careers in biomaterials and regenerative medicine.

The increasing production of greenhouse gas carbon dioxide (CO2) by human activities reached in 2021 more than 36 Gt and thus CO2 is generally considered as the biggest waste contributed to climate change. Current research is trying to address this challenge by capturing CO2 and using it as sustainable feedstock for polymer synthesis. The aim of this work is to investigate the possibilities of converting CO2 into polymer materials. The first route will be the CO2-oxirane (epoxy) coupling reaction, which leads to production of various cyclic carbonates, which are monomers for innovative polymer materials, e.g. non-isocyanate polyurethanes (NIPUs) and epoxides. The second approach will be the direct CO2 transformation into polycarbonates (PC). The third way will involve the ring-opening copolymerization of epoxide with CO2 leading to linear carbonate-ether copolymers. All the above-mentioned strategies will preferable utilize bio-based monomers to obtain fully renewable polymer materials. The important part of this PhD topic will be finding a suitable catalytic system for each synthetic path. Our preliminary experiments showed the successful CO2-epoxy cycloaddition in the presence imidazolium and metal-based ionic liquids (ILs). Due to ILs’ countless possible anion/cation combinations and their exceptional set of properties (low vapor pressure, negligible flammability, high thermal and chemical stability), they can seem to be suitable candidates to catalyze the cycloaddition reaction of epoxide and CO2 with tunable selectivity towards linear / cyclic carbonate and ether formation. As part of the doctoral project, a student's several-month internship at foreign collaborating workplace (INSA Lyon, France) is assumed. The candidates should have good communication skills in English (both in speaking and writing), should be able to work both in a team and independently. Active participation on foreign internships, trainings and scientific conferences is expected.

Polymeric micelles and nanoparticles are studied in the field of drug delivery and targeted drug release, especially in anticancer therapy. Thanks to their size (20-1000 nm), they accumulate in tumors due to the enhanced permeation and accumulation (EPR) effect. They protect incorporated drugs during transport and help to solubilize poorly soluble drugs. The potential thermoresponsive behaviour of the polymers used avoids the complicated techniques common to the preparation of micelles and other nanoparticle-based systems. The presence of suitable hydrolytically labile groups in the structure of the polymers can be exploited to ensure the gradual degradation of the nanoparticles and to ensure excretion of the polymer from the organism. With the intention of preparing nanoparticles with thermoresponsive and pH-sensitive properties, amphiphilic diblock copolymers consisting of a fully hydrophilic block, e.g., poly[N-(1,3-dihydroxypropyl)(meth)acrylamide] and an amphiphilic block, e.g., poly[N-(2,2-dimethyl-1,3-dioxan-5-yl)(meth)acrylamide], will be prepared by controlled radical RAFT polymerization. The associative behaviour of the copolymers in aqueous solutions, the formation and disintegration of nanoparticles or micelles will be studied by various physicochemical methods, e.g. size-exclusion chromatography, dynamic light scattering, NMR and transmission electron microscopy. The proposed systems offer the possibility to transport in particular anticancer drugs.

Polymeric micelles and nanoparticles are studied in the field of drug delivery and targeted drug release, especially in anticancer therapy. Thanks to their size (20-1000 nm), they accumulate in tumors due to the enhanced permeation and accumulation (EPR) effect. They protect incorporated drugs during transport and help to solubilize poorly soluble drugs. The potential thermoresponsive behaviour of the polymers used avoids the complicated techniques common to the preparation of micelles and other nanoparticle-based systems. The presence of suitable hydrolytically labile groups in the structure of the polymers can be exploited to ensure the gradual degradation of the nanoparticles and to ensure excretion of the polymer from the organism.

Annotation

High-Throughput Screening (HTS) is a key technology in the early stages of drug discovery. Interpreting results can be complicated by the presence of nuisance compounds behavior (PAINS, aggregators, autofluorescence, cytotoxicity, and others) that obscure the distinction between true and false positives. Metadata-rich datasets from the CZ-OPENSCREEN and EU-OPENSCREEN infrastructures, as well as large public repositories, such as PubChem, provide opportunity to better understand existing patterns, as well as identify new ones. This context-aware methodology aims to investigate how compound structures, experimental setup, and chosen biological targets relate to observed nuisance behavior. The work involves compiling, annotating, and developing tools for detecting and interpreting nuisance compounds, including substructure filters, curated compound lists, machine-learning models, and their composite approaches. Particular focus is given to distinguishing different nuisance mechanisms, highlighting the likelihood and severity of various flags, and their combinations, and compiling these insights into interpretable, human-readable formats. This work also involves exploring the use of large language models to generate clear, context-sensitive labels and descriptions. These tools can be packaged into open-access resources for compound triage and integrated into the CZ-/EU-OPENSCREEN ecosystem, with the CZ-OPENSCREEN facility offering their experimental validation.

In tissue engineering, vascularization of polymer scaffolds developed for tissue replacement is crucial for their functionality in the recipient body. Direct administration of free pro-angiogenic proteins (e.g., VEGF or FGF-2) often fails to produce effective results. Polymer-based delivery systems, such as nano- and microparticles, enabling controlled and localized release of growth factors, are therefore intensively studied. The PhD project aims to develop polyelectrolyte nano- and microparticles based on charge-shifting poly(dimethylaminoethyl acrylate) (PDMAEA) polycations for the controlled growth factor delivery. The gradual loss of charge on PDMAEA enables controlled particle degradation, sustained release of growth factors, and reduced toxicity, making these systems attractive for biomedical applications. The doctoral research will focus on i) the synthesis of PDMAEA-based block copolymers via RAFT polymerization to tune the particle charge density and corona composition, ii) the preparation of polyelectrolyte particles and characterization of their physicochemical properties (DLS, zeta potential measurements, IR spectroscopy, ITC, TEM), iii) investigation of protein loading and release behavior using ELISA, and iv) the evaluation of particle biocompatibility and protein bioactivity in collaboration with biologists. The interdisciplinary topic focuses on polymer chemistry and biomedical applications and is suitable for graduates of chemical disciplines such as macromolecular chemistry, physical chemistry, biochemistry, etc.

Bacterial infections, particularly those of the biofilm type, represent an increasing challenge for modern medicine, primarily due to rising antibiotic resistance. Cationic amphiphiles are highly effective local bactericides; however, for practical use on wounds, mucosal surfaces, or technical materials, it is often more advantageous to apply them not as concentrated solutions but in the form of controlled-release systems. Such formulations enable the long-term maintenance of lower, yet still bactericidal, concentrations of these agents, which are no longer harmful to human tissues. The aim of this doctoral dissertation is to prepare amphiphilic polyanions with varying structures and charge densities designed for the encapsulation and controlled release of micelles of cationic bactericides. The work will focus on elucidating the relationships between the structure of the polyanion and the bactericide, the efficiency of supramolecular encapsulation based on Coulombic interactions, the structure of the resulting polyplexes, and the release kinetics of the active component as influenced by temperature, ionic strength, and pH, as well as the associated bactericidal effects. A broad range of physicochemical methods will be employed to characterize these systems, including scattering techniques, fluorescence spectroscopy, isothermal titration calorimetry, and biological assays of antibacterial activity.

The project is focused on the development, synthesis and characterization of novel polymer particles in colloidal form for therapeutic and diagnostic purposes via intranasal administration. The particles will be prepared by heterogeneous polymerisation techniques (dispersion or precipitation) and the main polymerisation reaction will be based on an aromatic substitution mechanism. Bioanalogic substances derived from aromatic structures of plant and animal origin will be used as monomers. The influence of reaction conditions on the morphology and composition of polymer particles and other physicochemical parameters determining the behaviour of polymer particles in biological environments will be studied. Subsequently, the particles will be derivatized for their detection using preclinical imaging methods so that their biodistribution and pharmacokinetics can be monitored after intranasal administration. Biological testing of the particles will be performed at the collaborating departments of the UEM CAS and the 1st Faculty of Medicine of the Charles University. The aim of this collaboration is to describe how the composition and morphology of the particles from the new polymer types affects the mechanism of each type of intranasal delivery further into the body. The researcher will be based in the laboratories of the Institute of Macromolecular Chemistry at the BIOCEV Biotechnology Centre.

Type 2 diabetes is a serious metabolic disorder characterized by insulin resistance and the gradual failure of pancreatic ?-cells, leading to chronic hyperglycemia and the subsequent development of severe vascular, metabolic, and hormonal complications. Modern therapies employing GLP-1 agonists (e.g., liraglutide, semaglutide, or dulaglutide), which activate GLP-1 receptors on the surface of ?-cells, significantly improve glycemic control. However, their efficacy is limited by a short circulation half-life, rapid proteolytic degradation, and suboptimal receptor interaction, necessitating frequent dosing. The aim of this project is to develop innovative conjugates of GLP-1 peptide agonists with biocompatible polymeric carriers that provide prolonged therapeutic action, enhanced stability, and more efficient interaction with GLP-1 receptors on target cells. The project also includes the integration of imaging-enabled structural motifs to allow monitoring of conjugate biodistribution and quantification of labeled ?-cells using magnetic resonance or fluorescence-based techniques. Key emphasis will be placed on the rational design, synthesis, and detailed physicochemical characterization of water-soluble polymers based on phospho- and fluorinated polymer platforms, as well as their selective conjugation to GLP-1 agonists. The resulting conjugates will be evaluated in collaboration with domestic research partners (IKEM, FGÚ AV ČR) through both in vitro and in vivo studies, with the aim of monitoring pancreatic ?-cell populations and assessing the conjugates’ ability to effectively stimulate insulin production.

Diabetes 2. typu je závažné metabolické onemocnění charakterizované inzulinovou rezistencí a postupným selháváním pankreatických ?-buněk, což vede k chronické hyperglykemii a následnému rozvoji závažných vaskulárních, metabolických a hormonálních komplikací. Moderní terapie využívající GLP-1 agonisty (např. liraglutid, semaglutid či dulaglutid), které aktivují GLP-1 receptory na povrchu ?-buněk, výrazně zlepšují glykemickou kontrolu. Jejich účinnost je však omezena krátkým cirkulačním poločasem, rychlou proteolytickou degradací a omezenou účinností interakce s GLP-1 receptory, což vyžaduje časté dávkování. Cílem tohoto projektu je vývoj inovativních konjugátů GLP-1 peptidových agonistů s biokompatibilními polymerními nosiči, které zajistí prodloužený terapeutický účinek, zvýšenou stabilitu a efektivnější interakci s GLP-1 receptory cílových buněk. Součástí návrhu je také integrace struktur umožňujících sledování biodistribuce konjugátů a kvantifikaci označených ?-buněk pomocí magnetické rezonance či fluorescenčních metod. Hlavní pozornost bude věnována racionálnímu návrhu, syntéze a detailní fyzikálně-chemické charakterizaci vodorozpustných polymerů na bázi fosfopolymerů a fluoropolymerů a jejich specifické konjugaci s GLP-1 agonisty. Vzniklé konjugáty budou následně ve spolupráci s tuzemskými pracovišti (IKEM, FGÚ AV ČR) testovány in vitro i in vivo s cílem monitorovat počet pankreatických ?-buněk a posoudit jejich schopnost efektivně stimulovat produkci inzulinu.

Nanomedicines gain much more relevance in biomedical applications if they are tailored to be degradable in response to certain external stimuli. Such stimulus may be enzymatic removal of protecting groups, a pH change, light or the presence of reactive oxygen species (ROS) in cancer. Herein, imbalances on the cells micro-environment (pH changes, ROS production) will be explored for the synthesis of stimuli-responsive polymers and block copolymers. Inspired by the ease and effectiveness of the self-assembly of amphiphilic block copolymers in solution, several polymer nanomedicines, i.e., micelles, nanoparticles and vesicles will be designed to display tunable stimuli degradation in the presence of physiologically relevant changes in pH, temperature or ROS concentrations and will be prepared by microfluidic nanoprecipitation. This technique allows us the production of uniform particles with controllable size, shape and surface chemistry in a reproducible manner. The produced polymer self-assemblies will be characterized using standard scattering techniques (DSL/SLS/ELS, SAXS and SANS) and by microscopy. The effectiveness of the polymer nanosystems will be evaluated in in vitro and in in vivo models simulating the physiological balanced and imbalanced of the microenvironment.

The plastic waste treatment and a sustainable use of synthetic polymers is one of the major environmental challenges of the 21st century. Polyisocyanurate (PIR) foams are highly rigid foams primarily used for thermal insulation in construction, refrigeration, and other industries. They are produced by reacting polyols (which are typically derived from petroleum-based products) with isocyanates, resulting in a foam that has excellent insulating properties and resistance to fire and heat. PIR foams are chemically similar to polyurethane foams, but they have higher degree of isocyanurate content, which enhances their thermal stability and fire resistance. Recycling PIR foams is therefore challenging because their covalent structure is highly crosslinked and contains hydrolytically highly resistant structures that do not easily undergo chemical depolymerization. The aim of the PhD topic is to study the degradation behavior of PIR foams with the aim of finding a suitable method for their chemical recycling (solvolysis). The PhD candidates should have good communication skills in English (both in speaking and writing), should be able to work both in a team and independently. Active participation on foreign internships, trainings and scientific conferences is expected.

In the body, such biofilms are created on the surface of the medical devices, e.g., joint prostheses or heart valves, where they cause inflammation and chronic infections. The aim of this Ph.D. project is to develop a novel class of smart self-cleaning antibiofilm polymer surfaces, based on poly(2-alkyl-2-oxazoline)s, that are both anti-fouling and able to catalytically prevent the biofilm formation in the very long-term period. The project work includes polymer synthesis, the surfaces preparation and the study of their physicochemical properties. Moreover, the selected surfaces will be subjected to comprehensive in vitro and in vivo testing in the collaboration with biologists.

The aim of this PhD topic is to prepare and characterize polymer materials based on renewable raw materials (carboxylic acids, vanillin derivatives, furan compounds, etc.). The prepared materials will be dynamically crosslinked through reversible covalent bonds and non-covalent interactions (hydrogen bonding, metal-ligand coordination bonds, complex formation or electrostatic/ionic interactions), which will give the material self-healing and recyclable properties. As part of the doctoral project, a student internship of several months at a foreign collaborating institution (Cracow University of Technology, Poland) is planned. Applicants should have good communication skills in English (spoken and written), and should be able to work in a team and independently. Active participation in foreign internships, trainings and scientific conferences is expected.

Self-assembly of (macro)molecules is of crucial importance in the architecture of living organisms. Supramolecular systems have their key properties critically dependent on self-assembly and find use in the area of biomedical applications especially if they are able to reversibly react to external stimuli (changes in pH, light, redox potential, ultrasound, temperature, concentration of certain substances). The doctoral thesis will be based on chemical and/or physicochemical preparation and study of self-assembly of such multi-stimuli-responsive nanoparticles with external environment (pH, redox potential and temperature responsiveness); the exact topic will take into account the student´s interests. The studied nanoparticles and injectable depot systems will be designed for diagnostics and personalized immunoradiotherapy and immunochemotherapy of cancer and autoimmune diseases. Optimized nanoparticles will be then provided to collaborating biological workplaces for in vivo testing.

Ion-exchange polymer membranes are widely used in laboratory and industrial applications. Major applications include electrochemical desalination of seawater and brackish water, wastewater treatment, separation of mixtures in the production of industrial chemicals and pharmaceuticals, separation of electrolytes from non-electrolytes in electrochemical devices such as electrolyzers, fuel cells and batteries. Recently, their use in hydrogen management and storage of excess electricity from renewable sources has become increasingly important. The use of so-called green hydrogen produced in electrolyzers is one of the ways in the transition to carbon-free energy. The topic includes the synthesis of polymers and polymer membranes bearing functional groups for a specific purpose. For example, sulfo and phosphono groups for cation-exchange or quaternary ammonium groups for anione-exchange materials. In addition, these polymers are useful for electrode design, as catalyst supports and for other applications. Preparative organic chemistry and polymerization reaction methods are commonly applied. Our department is flexible enough to give the potential candidate enough room to apply his or her ingenuity.

Releasing and accumulating contaminants, especially residues from pharmaceutical products, pose health risks to humans and have a negative and significant impact on the environment. This research focuses on the development of innovative nanocomposites derived from biomass-based monomers and biopolymers for the removal of environmental contaminants. The relationship between the structure and properties of materials for contaminant sorption is still not fully understood, which limits their effectiveness. The scope of this work will first involve the synthesis and comprehensive structural characterization of the prepared nanocomposites, including porosity, stability, mechanical and thermal properties, to explain their efficiency in terms of macromolecular structure and the presence of active sites. The second research objective will be the evaluation of nanocomposites in terms of their sorption efficiency. Sorption kinetics will be studied to identify the mechanism and rate of the sorption process. The third part of the research will focus on the biodegradation of the nanocomposites after sorption in bioreactors using effective microbial cultures (such as activated sludge). The efficiency of pollutant biodegradation within the nanocomposites will be monitored, followed by the biodegradation of the nanocomposite materials themselves. During the biodegradation process, the degradation mechanism and potential degradation products will be observed and analyzed using selected analytical techniques. This project offers an alternative to conventional methods, aiming to minimize environmental impacts and improve the efficiency of environmental technologies.

Polymer membranes are widely used in separation processes due to their versatility, efficiency, and cost-effectiveness. These membranes are designed to selectively allow certain molecules or ions to pass through while blocking others, making them ideal for applications like water filtration, gas separation, and dialysis. Polymer membranes can be tailored for specific separation tasks by adjusting factors such as pore size, chemical composition, and surface properties. Their applications range from purifying drinking water through reverse osmosis to separating gases in industrial processes. With ongoing advancements, polymer membranes continue to play a crucial role in improving the sustainability and performance of various separation technologies. The subject matter encompasses the synthesis of novel polymers and the functionalization of commercially available materials, with a particular focus on their use in the separation of chemical mixtures, including gases and enantiomeric mixtures. Methodologically, the work will encompass polymerization reactions, the introduction of functional groups into polymers, and the utilization of reactions employed in preparative organic synthesis. Our department is sufficiently flexible to allow the prospective candidate the opportunity to exercise their inventiveness.

Biocompatible polymer ions have been intensively studied as promising materials in the therapeutical and diagnostical fields of nanomedicine. Recently, it was demonstrated that polyanions with a high charge density are able to suppress the biological effects of the cationic amphiphilic peptide (CAMP) melittin from bee venom by binding it to the polyplex complex. In the future bio-inspirited nanostructures loaded by toxic drug inside release the drug in the needed place. Drug will be honey bee poison melittin. Needed place will be cancer. The cathelicidin is an element of innate immunity, that plays an important role in the development of the pathogenic process in psoriasis. Both cathelicidin and defensins are CAMPs are expected to behave similar to mellitin from the point of view of interaction with polyanions such as polyacrylic acid. Thus, scavenging these peptides by locally administered polyanions should break the cytokine storm cycle, leading to the induction of psoriasis, and thus suppress it. The series of nanogels acids will be prepared using microemulsion polymerization technique. In vitro testing (hemolysis on mouse erythrocytes) of obtained materials will be performed. Chemical, physical and biomedical investigation will be performed.

Biokompatibilní polymerní ionty byly intenzivně studovány jako slibné materiály v terapeutické a diagnostické oblasti nanomedicíny. Nedávno bylo prokázáno, že polyaniony s vysokou hustotou náboje jsou schopny potlačit biologické účinky kationtového amfifilního peptidu (CAMP) melittinu z včelího jedu jeho vazbou na komplex polyplex. V budoucnu bioinspirované nanostruktury naložené toxickým lékem uvnitř uvolňují lék na potřebném místě. Jako lék bude včelí jed melittin. Potřebným místem bude nádor.Katelicidin je prvek vrozené imunity, který hraje důležitou roli ve vývoji patogenního procesu u psoriázy. Očekává se, že jak katelicidin, tak defensiny se budou chovat podobně jako mellitin z hlediska interakce s polyaniony, jako je kyselina polyakrylová. Vychytávání těchto peptidů lokálně podávanými polyaniony by tedy mělo přerušit cyklus cytokinových bouří, což by vedlo k indukci psoriázy, a tím její potlačení. Řada nanogelových kyselin bude připravena technikou mikroemulzní polymerace. Bude provedeno In vitro testování (hemolýza na myších erytrocytech) získaných materiálů. Bude provedeno chemické, fyzikální a biomedicínské vyšetřování.

Quantum dots (QDs) are semiconductor nanoparticles with outstanding optoelectronic properties. More specifically, QDs are highly bright and exhibit wide absorption spectra, narrow light bands, and excellent photovoltaic stability, which make them useful in bioscience and medicine, particularly for sensing, optical imaging, cell separation, and diagnosis. In general, QDs are stabilized using a hydrophobic ligand during synthesis, and thus their hydrophobic surfaces must undergo hydrophilic modification if the QDs are to be used in bioapplications. Silica-coating is one of the most effective methods for overcoming the disadvantages of QDs, owing to silica’s physicochemical stability, nontoxicity, and excellent bioavailability. Micro and nano-particles of SiO2 will be covered by polydopamine, or by mixture of citric acid and urea, or by melamine. The covered layer will be carbonized in the presence of conducting metal ionically connected to the covered layer. The entire SiO2 can be dissolved. Rest hollow charged particles will be examined by electrochemical, fluorescent methods and other techniques needed for characterization of quantum dots.

Kvantové tečky (QD) jsou polovodičové nanočástice s vynikajícími optoelektronickými vlastnostmi. Přesněji řečeno, QD vykazují široká absorpční spektra, úzké světelné pásy a vynikající fotovoltaickou stabilitu, díky čemuž jsou užitečné v biovědě a medicíně, zejména pro snímání, optické zobrazování, separaci buněk a diagnostiku. Obecně se QD během syntézy stabilizují pomocí hydrofobního ligandu, a proto jejich hydrofobní povrchy musí projít hydrofilní modifikací, pokud mají být QD použity v bioaplikacích. Oxid křemičitý je jednou z nejúčinnějších metod pro překonání nevýhod QDs díky fyzikálně-chemické stabilitě, netoxicitě a vynikající biologické dostupnosti oxidu křemičitého. Mikro a nanočástice SiO2 budou pokryty polydopaminem nebo směsí kyseliny citronové a močoviny nebo melaminem. Pokrytá vrstva bude karbonizována v přítomnosti vodivého kovu iontově spojeného s pokrytou vrstvou. Celý SiO2 může být rozpuštěn.

Projekt je zaměřen na přípravu a studium ve vodě rozpustných uhlíkatých radikálů s fluorescenčními skupinami pro přímou neinvazivní opakovatelnou kvantifikaci rozpuštěného molekulárního kyslíku, které umožní měření i v buňkách a cévách. Kvantifikace hladin kyslíku in vitro a in vivo je důležitá nejen pro pochopení fyziologických procesů, ale také pro hodnocení a terapii patologických stavů, např. nádorů, onemocnění periferních cév, zánětů a ran. Je extrémně náročné získat přesné hodnoty oxygenace v buňkách nebo tkáních v mikroskopickém měřítku. V tomto projektu kombinujeme dvě nejvhodnější techniky pro tento účel vytvořením jediného bimodálního molekulárního detektoru. Metoda detekce kyslíku je založena na rozšíření EPR čáry způsobené paramagnetickými molekulami O2 padajícími v blízkosti radikálu a druhá je založena na zhášení fluorescence nebo zkrácení životnosti fluorescence v důsledku interakcí s kyslíkem. K detekci budou použity dva typy zařízení - elektronový paramagnetický rezonanční spektrometr a konfokální mikroskopie vybavená doplňkem fluorescenčního zobrazování (FLIM). Molekuly budou také testovány na 3D buněčných kulturách (sféroidech).

Treatment of hypoxic tumors is complicated due to higher radio/chemo resistance resulting in the subsequently lower clinical outcome of the treatment. We propose to explore a new concept of self-assembled polymer radiosensitizers to overcome the problem low hypoxic tumor radiosensitivity. The proposed approach is based on restoration of radiosensitivity of hypoxic cancer tissue by actively hypoxia-targeted delivery of reactive oxygen species (ROS)-precursors as well as on selective decomposition of hydrogen peroxide in hypoxic tissue influencing the HIF-1 alpha system. The proposed concept utilizes hydrophilic biocompatible polymer-based carriers with hypoxia-targeting nitroaromatics systems. The doctoral thesis will be based on synthesis, chemical and/or physicochemical characterization and study of self-assembly properties of such multi-stimuli-responsive nanoparticles with external environment; the exact topic will take into account the student´s interests.

Poly(glycerol sebacate) (PGS) is a biocompatible, biodegradable polyester with tunable mechanical properties, representing a promising alternative to non-degradable biomaterials—particularly for soft tissue regeneration and other applications requiring flexible elastomeric scaffolds. This PhD project aims to address current challenges in the 3D printing of PGS, which include optimizing the composition and viscosity of printable “inks,” developing efficient cross-linking methods, whether photo-induced or enzyme-mediated, and improving the biocompatibility of highly hydrophobic PGS through 3D printing of blended inks with biopolymers such as collagen. The student will gain experience in various synthesis techniques, 3D printing methods, and material characterization procedures using modern instrumentation (GPC, ?H and ??C NMR, UV/VIS and fluorescence spectroscopy, Cellink BioX 3D printer, electron and optical microscopy, rheological measurements). A background in polymer chemistry, organic chemistry, or biomaterials is an advantage but not a requirement — what matters most is a willingness to learn and explore new areas in these fields.

Poly(glycerol sebacate) (PGS) is a biocompatible, biodegradable polyester with tunable mechanical properties, representing a promising alternative to non-degradable biomaterials—particularly for soft tissue regeneration and other applications requiring flexible elastomeric scaffolds. This PhD project aims to address current challenges in the 3D printing of PGS, which include optimizing the composition and viscosity of printable “inks,” developing efficient cross-linking methods, whether photo-induced or enzyme-mediated, and improving the biocompatibility of highly hydrophobic PGS through 3D printing of blended inks with biopolymers such as collagen. The student will gain experience in various synthesis techniques, 3D printing methods, and material characterization procedures using modern instrumentation (GPC, ?H and ??C NMR, UV/VIS and fluorescence spectroscopy, Cellink BioX 3D printer, electron and optical microscopy, rheological measurements). A background in polymer chemistry, organic chemistry, or biomaterials is an advantage but not a requirement — what matters most is a willingness to learn and explore new areas in these fields.
