Chitosan is the most abundant natural biopolymer, after cellulose. It is mainly derived from
the fungi, shrimp's shells, and exoskeleton of crustaceans, through the deacetylation of
chitin. The ecological sustainability associated with its exercise and the flexibility of chitosan
owing to its active functional hydroxyl and amino groups makes it a promising candidate for
a wide range of applications through a variety of modifications. The biodegradability and
biocompatibility of chitosan and its derivatives along with their various chemical …
