Wound dressing applications of chitosan and its derivatives: a short review

Chitosan is a biopolymer with structural function that could be derived from chitin that is the second most available biopolymer in the nature. This valuable macromolecule is biocompatible, biodegradable, non-toxic and is reported to have antibacterial and wound healing effects. It is easy to supply and not expensive. Furthermore, it is suitable in terms of transparency and film forming ability as it can be modified into different forms and be used for different purposes. All of these features, make chitosan a promising candidate to be utilized for fabrication of wound dressing materials with different capabilities. This paper is intended to review the potential properties of chitosan wound dressing and talk shortly about its applications in wound care supplies.
