Annotation:The goal of this project is to develop tissue-engineered articular cartilage using an injectable shear-thinning hydrogel administered in a minimally invasive way into living bodies, with the ability to match irregular defects and fulfill most of the requirements for cartilage regeneration. This hydrogel will be formed based on bioorthogonal chemistry through the combination of both dynamic supramolecular and covalent crosslinks. The intention is to improve the mechanical properties to mimic the extracellular matrix (ECM) of articular cartilage without compromising the biocompatibility of the hydrogel. Simultaneously, the hydrogel composition will be modulated to meet the fundamental requirements of the scaffold in treating cartilage, including (i) bioadhesion, (ii) promotion of chondrogenesis, and (iii) biodegradation without toxic by-products. The performance of the proposed platform will be tested in a rabbit model for cartilage regeneration. Dosiahnuté výsledky: Throughout this year, our main focus was on different aspects of polymer library preparation. We synthesized the essential polymer library crucial for the development of injectable hydrogels. As an initial experiment, we devised and created crosslinked injectable hydrogels utilizing both non-covalent and covalent bonds. We assessed the impact of covalent bonds, particularly hydrazone bonds, on the properties of the injected hydrogel, including its chemical and mechanical stability.

Konštrukcia inteligentných polymérnych kompozitných systémov pre kontrolované a cielené podávanie liečiv.

Annotation:The overall objective of this project is to develop and evaluate new smart bioactive composites for controlled and targeted drug delivery. These systems will be constructed in forms of bioactive hydrogel Nanocomposites based on modified natural polymers and bioactive MOFs materials. It is expected that the presence of biopolymer derivatives not only leads to the biodegradability and biocompatibility of the system but also leads to the release of anticancer drugs to a greater extent at pH. In addition, functionalization of biopolymer with an extra amine and carboxylic groups is expected to provide stimuli responsive character for the constructed bionanocomposite carrier. Additionally, these platforms will be fabricated in form of duel layered core-shell hydrogel composites microcapsules through polyelectrolyte complex formation based on maodified natural polymers in combination with bioactive Graphene Oxide derivative. These polyelectrolyte complexes are expected to custimize the targeted and controlled drug release profiles. Finally, it is aimed also to construct grafted biocomposie hydrogels based on β-cyclodextrin grafted biopolymer and MOFs and/or GO-derivatives materials as smart pH-sensitive drug carriers.

Annotation:The goal of the project is to develop biocompatible alginate-based microspheres stabilized by dual ionic and dynamic covalent crosslinks with self-healing characteristics. The intention is to enhance the chemical and mechanical durability of the microspheres by incorporating dynamic bonds into their network and mitigating foreign body responses using anti-fibrotic agents located on the microsphere surface. These crucial features of microspheres will be tuned through alterations in the alginate backbone by introducing various contents of bio-clickable and anti-fibrotic agents.
