Chronic wounds affect 1-2% of the population. In the presented study, chitosan-coated and chitosan-containing liposomes were prepared to enhance the antibacterial effect of the drug chlorhexixdine. A chitosan-based delivery system enhances the antimicrobial activity of chlorhexidine.

Good dentures are becoming increasingly important as the population ages. Conventional materials for the base of dentures are often porous and thus susceptible to deformation or microbial colonization. To prevent this, chitosan is added to polymethyl methacrylate resin in the presented study.
