As you may know, chitosan is a polysaccharide produced by the alkaline deacetylation of chitin, a widely available biopolymer found in the exoskeleton of crustaceans such as crab and shrimp.
In this study, ATR-FTIR spectroscopy was employed to investigate the possible intermolecular interaction of Cytarabine with deacetylated chitosan and tripolyphosphate in the resulting physical blends and crosslinked nanoparticulate system.
The company, founded by a group of young entrepreneurs, is extracting chitosan from shrimp peels and using it to produce anti-bacterial chemicals and other materials used in the fields of agricultural and medicine.
Chitosan is a naturally occurring biopolymer obtained from crab or shells of shrimp.
In this study, Chitosan nanoparticles were prepared by electrospray method (electrohydrodynamic atomization) and parameters that simultaneously affect size and/or size distribution of chitosan nanoparticles were optimized.
Preparation and characterization of scaffold nanofibers by electrospinning, based on chitosan and fibroin from Silkworm (Bombyx mori)
The team did this by incorporating an antibacterial and biodegradable substance called chitosan, extracted from the shells of crustaceans, within the dressing itself.
ABSTRACT: The potential of chitosan extracted from crab exoskeleton as biosorbent for the removal of toxic Cr(VI) on waste water is investigated by doing preliminary adsorption experiment to determine the effect of contact time, pH, initial Cr(VI) concentration, dosage of biosorbent and particle size.
In the current study novel polymer composites were prepared using natural polymers chitosan and starch in molds.
The review, published in the journal Science and Technology of Advanced Materials, provides an overview of the different nanomaterials that are being tested in combination with chitosan, the methods used to prepare the composite materials and the resultant properties that make them suitable for applications in the biomedical field.
However, the investigation of its potential as a new raw material for chitosan production deserves to be highlighted, especially because they may be used as an alternative for people allergic to shrimp and other crustaceans.
