The chitosan structure can be varied in two ways, by changing the degree of acetylation of the glucosamine monomers, ie the charge of the polymer, or by changing the molecular weight. The ...

The drug delivery system should have mucoadhesive particles and release the drug over time. Due to the positive charge of chitosan, it can bind with the negatively charged mucus. Thus, chitosan can ...

A 1998 study determined that 22.3% of Americans were obese, [1] a more than 50% increase over the rate in the preceding decade. The frequency of obesity is rising in all age groups and all ethnic ...

However, polyethylene microplastics used in this study are nonpolar in nature, which makes it unlikely that they will have strong chemical interactions with chitosan based on charge. Further ...

The key is chitosan, a compound derived from chitin ... per square centimetre for 400 hours – or 1000 cycles of charge, which is comparable to small lithium batteries. “It is not an easy ...

But how healthy is the shell part of shellfish? While the shells themselves aren’t edible, chitosan is a supplement made from a substance found in the outer shells of crustaceans. It’s touted ...

A material known as chitosan, made from crustacean shells, has been used to substitute petroleum by-products in food packaging. The environment is seriously affected by the use of food packaing ...

This new battery, which could store power from large-scale wind and solar sources, uses a gel electrolyte made from a biological material called chitosan. "Chitosan is a derivative product of chitin.
