Quercetin-Crosslinked Chitosan Films for Controlled Release of Antimicrobial Drugs.

Natural polymer-based films, due to their favorable biological and mechanical properties, have demonstrated great potential as coatings for biomedical applications. Among them, chitosan films have been widely studied both as coating materials and as controlled drug release systems. Crosslinkers are often used to tune chitosan's crosslinking degree and thus to control the drug release kinetics.
