Biological Application of Chitosans

Abstract

Chitosan is a natural cationic polymer used for many medical and non medical applications. It is deriving mainly by the crustacean shells and fungal micelia following deproteinization and is considered as a non toxic and biodegradable polymer. Chitosan carries abundant amino groups with positive charges reacting with negatively charges substances. The most common uses will be presented, focusing on the main characteristics of this fiber. The activity as food supplement/dietetic/fat binder, its antimicrobial potential, the orthopedic application, the use in the pharmaceutical technology/drug delivery systems, and finally the use as wound and burns healing will be discussed.
