Description générale

Chitosan is a linear amino polysaccharide composed of approximately 20% β1,4-linked N-acetyl-D-glucosamine (GlcNAc) and approximately 80% β1,4-linked D-glucosamine (GlcN) that is prepared by the partial deacetylation of chitin in hot alkali.

Application

Chitosan is a biocompatible, antibacterial, and biodegradable polyelectrolyte with a variety of industrial and biomedical applications. Its chemical properties and low toxicity make it particularly suitable as a component of drug and gene delivery systems, and for the development of biodegradable films and scaffolds for tissue engineering.
