ABSTRACT
A rare, cationic mucopolysaccharide, chitosan (CS) is composed of d-glucosamine and N-acetyl-dglucosamine monomeric units. Produced from chitin, which is simply N-acetylated CS, it is nature’s most plentiful biopolymer after cellulose. Chitin and CS are present in cell walls of microbes such as fungi and form the basic skeletal material of invertebrates (Hirano 2002), thereby supporting numerous living organisms (Van et al. 2006). CS polymers have an assortment of important qualities such as biodegradability, compatibility, pH sensitivity, nonantigenicity, and nonallergenicity that make them signicant for biomedical applications.
