Application of Plant Based Natural Polymer in Drug Delivery System: A Critical Overview

Several natural polymers have been used for a variety of biomedical applications including drug targeting, pharmaceutical preparations, drug delivery systems, prosthetics, and tissue engineering scaffolds. Natural polymers can be classified into three classes like polysaccharides, proteins, and polyesters on the basis of chemical structures. Natural polymers are widely used because they are readily accepted by the body and possess high bioactivity and biocompatibility. Many researched are going on and novel natural polymers are to be expected in future. Applications of natural polymers derived from plants have been extensively explored in different drug delivery systems. This review article will be useful to upcoming scientists who are working on different delivery systems using natural polymers.
