Chitosan has garnered much interest due to its properties and possible applications. Every
year the number of publications and patents based on this polymer increase. Chitosan …

Nanochitin and nanochitosan (with random‐copolymer‐based multiscale architectures of
glucosamine and N‐acetylglucosamine units) have recently attracted immense attention for …

Chitin is the most abundant natural polysaccharide and chitosan is its most important
derivative. Regardless of having various bioactivities, the water insolubilities of chitin and …

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 …

Chitin, chitosan, and their derivatives are considered to promote diverse activities, including
antioxidant, antihypertensive, anti-inflammatory, anticoagulant, antitumor and anticancer …

Chitosan is a natural nontoxic biopolymer produced by alkaline deacetylation of chitin.
Chitin and chitosan are insoluble in water as well as most organic solvents. Chito-oligomers …

Chitosan (300 kDa) was degraded by cellulase to chitosans with molecular weights (MWs)
of 156, 72, 7.1, and 3.3 kDa and a chitooligosaccharide mixture (COS). Effects of these on …

Many studies have shown that mitochondrial metabolism has a fundamental role in
induction of carcinogenesis due to the influence of increased levels of reactive oxygen …

Chitosan's lack of solubility in physiological pH and high molecular weight (MW) limits its
use in hydrogel scaffolds. Conversion of chitosan to low MW chitooligosaccharides (COS) …

Chitosan oligosaccharides (COSs) are widely used biopolymers that have been studied in
relation to a variety of abnormal biological activities in the food and biomedical fields. Since …
