Chitosan Based Nanoparticles In Drug Delivery
Nanoparticles have gained considerable attention in recent years as one of the most promising drug delivery systems owing to their unique potentials via combining the different characteristics of hydrophilicity and hydrophobicity with a nanoparticle (e.g., very small size). Several polymeric nanoparticulate systems have been prepared and characterized in recent years, based on both natural and synthetic polymers, each with its own advantages and drawbacks. Among the natural polymers, chitosan has been studied extensively for preparation of nanoparticles. Chitosan nanoparticles have been reported with different characteristics with respect to drug delivery. This review presents various types of chitosan based nanoparticles in drug delivery.
