Chitosan, a naturally abundant cationic polymer, is chemically composed of cellulose-based
biopolymers derived by deacetylating chitin. It offers several attractive characteristics such …

Advanced development of chitosan hydrogels has led to new drug delivery systems that can
release their active ingredients in response to environmental stimuli. This review considers …

Chitosan oligosaccharide (COS) is an oligomer of β-(1➔ 4)-linked d-glucosamine. COS can
be prepared from the deacetylation and hydrolysis of chitin, which is commonly found in the …

This review outlines the new developments on chitosan-based bioapplications. Over the last
decade, functional biomaterials research has developed new drug delivery systems and …

Biodegradable chitin is the second-most abundant natural polysaccharide, widely existing in
the exoskeletons of crabs, shrimps, insects, and the cell walls of fungi. Chitosan and …

Chitosan is a natural polysaccharide that has attracted significant scientific interest during
the last two decades. It is a potentially biologically compatible material that is chemically …

Chitin, the second most important natural polymer in the world, and its N-deacetylated
derivative chitosan, have been identified as versatile biopolymers for a broad range of …

Shrimp has constituted a major part of crustacean consumption in recent years. Solid
wastes, including the head, shell, and tail portions, accumulate owing to shrimp processing …

Chitosan has received much attention as a functional biopolymer for diverse applications,
especially in pharmaceutics and medicine. Our recent efforts focused on the chemical and …

Chitosan oligosaccharides (COS) are the degraded products of chitin or chitosan prepared
by chemical or enzymatic hydrolysis. As compared to chitosan, COS not only exhibit some …
