Chitosan /ˈkaɪtəsæn/ is a linear polysaccharide composed of randomly distributed β--linked D-glucosamine and N-acetyl-D-glucosamine. It is made by treating the chitin shells of shrimp and other crustaceans with an alkaline substance, such as sodium hydroxide. Chitosan has a number of commercial and possible biomedical uses. It can be used in agriculture as a seed treatment and biopesticide, helping plants to fight off fungal infections. In winemaking, it can be used as a fining agent. مرکز تخصصی واردات و عرضه انواع کیتوسان های (chitosan) آزمایشگاهی و تحقیقاتی در انواع وزنهای ملکولی از شرکت سیگما ، شرکتهای هندی و چینی در حجمهای خرد و انبو Chitosan Powder is a linear polysaccharide composed of randomly distributed β- (1-4)-linked D-glucosamine (deacetylated unit) and N-acetyl-D-glucosamine (acetylated unit). It is made by treating shrimp and other crustacean shells with the alkali sodium hydroxide.Chitosan has a number of commercial and possible biomedical uses In contrast, un-modified chitosan (i.e. without hydrophobes) was unable to clot blood. The hydrophobias within HM-CHI entered into the RBC membranes and connected to the cells by a sample-spanning network, which subsequently led to the formation of an elastic gel. The gelling ability of HM-CHI is similar to that of fibrin-based sealants, but at.

  1. The proposed mechanism is that chitosan molecules adsorbed or printed on the PDMS surfaces act as reducing/stabilizing agents. Furthermore, PDMS films patterned with chitosan could induce localized synthesis of gold nanoparticles in regions capped with chitosan only. In this way, colloidal patterns were fabricated on the surfaces with high.
