Natural Polymers and their Application in Drug Delivery and Biomedical Field

Biodegradable polymers are widely being studied as a potential carrier material for site specific drug delivery because of its non-toxic,biocompatible in nature. Natural polysaccharides have been investigated for drug delivery applications as well as in biomedical fields. Modified polymer has found its application as a support material for gene delivery, cell culture, and tissue engineering. Now a day, the polymer is being modified to obtain novel biomaterial for controlled drug delivery applications. This review provides an overview of the different modified polymer derivatives and their applications with special attention being put on controlled drug delivery and biomedical engineering.
