Abstract
Chitosan, a biopolymer obtained through the partial deacetylation of
chitin, is widely valued for its biocompatibility, biodegradability, and
functional versatility. Traditionally sourced from marine crustaceans, chitosan
has recently gained attention from entomological origins, particularly due to
ecological concerns and allergenic issues associated with marine sources.
Insect-derived chitosan presents a sustainable and underutilized alternative
with comparable physicochemical properties and added environmental benefits.
This review explores the major biological sources of chitosan, focusing on
insects and marine organisms, and highlights their impact on polymer quality
and application potential. The intrinsic properties of chitosan such as
cationic nature, mucoadhesion, antimicrobial activity, and ease of chemical
modification support its wide-ranging use in pharmaceuticals, biomedicine,
agriculture, food preservation, and environmental remediation. Notably, its
application in drug delivery systems, wound healing, tissue engineering, and gene
therapy demonstrates its promise as a next-generation biomaterial. Advancements
in formulation science and nanotechnology further enhance chitosan’s
adaptability across sectors. This review underscores the importance of
expanding entomological sources of chitosan as a sustainable, cost-effective,
and eco-conscious strategy, bridging biomaterial science with environmental
responsibility. As research advances, insect-sourced chitosan is poised to play
a pivotal role in addressing global challenges through innovative biopolymer
applications.
