aAbstract: chitosan is a natural polymer flocculant, because of its non-toxic, non-polluting, and biodegradable, and in the chemical industry, textile, food, medicine, agriculture, membrane separation and other fields has been widely research and application. Chitosan application in the field of en...
PROBLEM TO BE SOLVED: To obtain a substance capable of eliminating the damage attributable to a heavy metal without disturbing the absorption of trace elements, which are essential to a plant, by a plant in order to solve a problem that although chitosan has chelate forming activity and is ...

A section is dedicated to the formulation of chitosan biomaterials, from gel to nanobeads, exploring their innovative application as active carrier nanoparticles. Finally, the toxicity issue of chitosan as a polymer and as a constructed nanomaterial is briefly commented in the conclusions. 展开 ...
10.2.1.1 Biodegradable polymer coatings Chitosan is a long-chain natural biopolymer obtained from chemical modification of chitin, the main component of crustacean shells. This linear polysaccharide is made up of randomly distributed β-linked d-glucosamine and N-acetyl-d-glucosamine subunits, and it ...
Chitosan is a natural cationic linear polymer that has recently emerged as an alternative nonviral gene delivery system. We have established the relationships between the structure and the properties of chitosan-pDNA polyplexes in vitro. Further, we have compared polyplexes of ultrapure chitosan (UPC...
Chitosan is poly-β(l→4)-2-amino-2-deoxy-β-D-glucan (Figure 13.1), deacetylated chitin. Chitin is widely found in crustacean shells, fungi, insects, annelids, mollusks, coelenterates, etc. (Muzzarelli 1990). Chitosan is produced commercially from chitin, the major component of crustacean...

It is a chemical that may naturally biodegrade. Chitosan that has undergone irradiation has had its molecules lightened by gamma radiation, which causes the breaking of chemical bonds. Because of the smaller chitosan molecules, plants can absorb and use it more quickly than they can with regular ...
