Abstract
Chitosan is a type of biopolymer that can be derived from various natural sources, including animals and marine organisms. When determining its quality, molecular weight, crystallinity, and degree of deacetylation of chitosan are considered. Biocompatibility, bioadhesive, solubility, and polycationic character are all based on these traits. Chitosan’s characteristics make it a good and appealing material for a variety of physical and chemical alterations. This review talks about the structure of chitosan and its properties. It also covers how chitosan is extracted from different sources. Special emphasis is placed on its utilization in the formation of metallic nanoparticles, drug delivery, and wastewater treatment.
