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 ...

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 ...

Natural polymers, such as chitosan, obtained from chitin, are been widely studied for use in the tissue regeneration field. This study established a protocol to attain membranes made from this biopolymer, consisting of ...

Recently, much attention has been given to pulmonary drug delivery by means of nanosized systems to treat both local and systemic diseases. Among the differentmaterials used for the production of nanocarriers, chitosan ...

The aim of this work was to evaluate the possibility of using mixtures and/or polyelectrolyte complexes from both chitosan-alginate and chitosan-carrageenan as prolonged drug release systems. Different dissolution profiles ...

The effect of chitosan addition on the structure and drug release properties of ureasil-polyethylene oxide (U-PEO) hybrid materials was examined. The hybrids and the blends were prepared by the sol-gel route and their ...
