Abstract

Chitin and chitosan, as the most abundant amino polysaccharides in nature, have characteristics such as high biocompatibility, low toxicity, biodegradability, and acceptable antimicrobial properties. These unique properties led Chitin and Chitosan to pay great attention not only in terms of the abundance of natural resources but also because of their high potential for the preparation of applied materials. Extensive improvements have been made in improving their properties for use in tissue engineering and medication, wound healing and relief agents. This paper tries to show a general perspective on the many applications of these biopolymers. The text ends with the description of the potential application of this material in building preservation.
