Abstract

Over the last decade, much interest has been developed in biopolymer based materials due to their biocompatible, biodegradable, non-toxic and non-allergenic nature. Chitosan is a unique biopolymer that exhibits outstanding properties, besides biocompatibility and biodegradability. Most of these peculiar properties arise from the presence of primary amines along the chitosan backbone. Many works have been done to obtain chitosan based scaffolds, including surface modifications, the fabrication of chitosan based blends, chitosan based composite scaffolds, and drug-loaded scaffolds. This study provides an overview of the key features of inherent properties of chitosan, their modification, and its use in biomedical engineering particularly toward anti-inflammatory and wound healing.
