Summary: Chitosan, as a biotechnological derivative of chitin, has various pharmaceutical and biomedical applications. It can encapsulate and deliver cancer therapeutics with specific drug targeting at the tumor microenvironment, enhancing cancer cytotoxic drug actions. To minimize off-target effects and drug-related adverse reactions, it is clinically necessary to achieve highly targeted drug delivery at the lowest possible drug doses.

Summary: Natural polymer-based films, specifically chitosan films, have been extensively studied as coatings for biomedical applications due to their favorable biological and mechanical properties. In this study, chitosan films crosslinked with quercetin were used as controlled release systems for the antibiotic drug trimethoprim. The results show that quercetin increases the crosslinking degree of chitosan films in a dose-dependent manner, affecting the release kinetics of the loaded drug while maintaining its antibacterial effects. This work demonstrates the potential of quercetin-crosslinked chitosan films as antibiotic-releasing coatings for biomedical applications.

Summary: Polymer hydrogels crosslinked by therapeutic metal ions have gained attention for their unique properties. Chitosan hydrogels have been widely studied in biomedical applications. This study investigated the properties of bimetallic-chitosan complex hydrogels with different cupric and zinc ions content. The results showed changes in morphology, formation of bimetallic-chitosan aerogels, decreased swelling ability and increased shear modulus with higher Cu content, and a strong physical crosslink between metal ions and chitosan chains.

Summary: In this study, chitosan was crosslinked using glycyrrhizic acid as a new crosslinking agent, and the obtained hydrogels showed biocompatibility for controlled release of gallic acid in transdermal therapy. The crosslinking of chitosan with glycyrrhizic acid formed a covalent amide linkage, resulting in the formation of a crosslinked hydrogel network structure.

Summary: Chitosan scaffolds have great potential in biomedical applications, particularly in bone tissue engineering. This study successfully achieved controlled drug release in chitosan scaffolds by incorporating drug carriers, specifically for the osteoporosis drug risedronate. The addition of zeolite to the chitosan scaffold resulted in better drug retention compared to hydroxyapatite, demonstrating promising results for the potential use of this material in bone tissue engineering.
