Chitosan is a cationic polysaccharide with linear chain consisting of β-(1,4)-linked 2-acetamino-2-deoxy-β-D-glucopyranose and 2-amino-2-deoxy-β-D-glucopyranose. It does not show any adverse effects when in contact with human cells and this property has attracted chemist’s scientific attention to chitosan. The biological activities of chitosan make it promising agent in controlled drug delivery systems, which can control the release of drug for long period of time. Chitosan also has antimicrobial activity, wound-healing properties, and can decrease the level of cholesterol inhuman body
