Chitosan: introduction and its role as a drug delivery vehicle

Nowadays, nanoparticles has revolutionized the concept of drug targeting system and there are various nanoparticle available around us and from that one of them is Chitosan. Chitosan is a mucopolysacharide and it is the biproduct of exoskeletons in crustaceans. The chitosan nanoparticles is considered as a safe material due to its biocompatibility, better stability, low toxicity, simple preparation methods and it act as a very good adjuvant for the process of drug delivery and thusact as a valuablevehicle for the delivery of drugs in the present era. The present review highlights about various aspects of chitosan and how it holds promise as a suitable material for biomedical applications. The predicted aspects of chitosan’s targeting area in human has been discussed here for the first time.
