Biomedical Applications of Chitosan
In the past few decades, extensive researches are being undertaken to develop innovative drug delivery systems and improve scaffolds for regenerative/alternative substances that are currently one of the most rapidly growing fields of modern science. Chitosan (CH) is a copolymer, composed of glucosamine and N-acetylglucosamine, and considered as a polycationic, biocompatible, and biodegradable polymer. It is one of the most explored and studied polymers. It bears several reactive functional groups, which make it capable of possessing strong biological properties with less toxicity, biodegradability, and environmental compatibility. Due to its low solubility, it has limitation for biomedical purposes. Chemical modification into composites or hydrogels provides versatile biomaterials because of their nontoxicity, low allergenicity, biocompatibility, and biodegradability. This chapter discusses the several biomedical applications of CH.
