Chitosan beads
WebChitosan (CS), a cationic, hydrophilic polysaccharide extracted from chitin, is composed of N-acetylglucosamine units that are β- (1–4) linked with D-glucosamine repeating units. Due to its cationic substrate, the + NH 3 groups, CS may interact or form a complex bond with other anionic surface.
