The electrochemical behavior of the cationic polymer chitosan-gtmac (Ch-GTMAC), at the polarized water / 1,2-dichloroethane interface was studied. This polymer was obtained by nucleophilic reaction of chitosan (Ch) with ...

This article reports on modified chitosan as an alternative substance for protecting loss of volatile compounds during freeze drying. Moisture sorption isotherms of freeze-dried D-limonene emulsions in modified chitosan ...

Chitosan, a polyaminosaccharide obtained by alkaline deacetylation of chitin, possesses useful properties including biodegradability, biocompatibility, low toxicity, and good miscibility with other polymers. It is extensively ...

A large number of carboxylic groups were introduced onto chitosan by grafting with poly(acrylic acid) as an efficient way of modification. The reactions were carried out in a homogeneous aqueous phase by using potassium ...

The interaction of chitosan and its N-dodecyl and poly(ethylene glycol) derivatives with 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) vesicles was studied to evaluate the influence of molecular architecture of the ...

Mercury (Hg) is one of the most toxic heavy metals commonly found in the global environment. Its toxicity is related to the capacity of its compounds to bioconcentrate in organisms and to biomagnifie through food chain. A ...

Chitosan polymer as a bioactive carrier has an emerging importance due to its great versatility. Many strategies are reported for enhancing its properties. Herein, chitosan hydrogels modified by dodecenylsuccinic anhydride ...

Banana starch was oxidized at three different levels and afterwards acetylated. The double-modified starch was used for film preparation with the addition of chitosan. The physical, mechanical, and barrier properties were ...
