Chitin and chitosan (a deacetylated derivative of chitin) have been proposed for biomedical applications because of their biocompatibility and abundance in nature. We have investigated the effect of the percentage of deacetylation (%DD) of chitosan on biocompatibility from two sources, shrimp and cuttle fish, with two cell lines, L929 and BHK21(C13). The(More)
The fusion protein technique was used to prepare an artificial polyfunctional protein from calmodulin (CaM) and glutathione S-transferase (GST). The fusion protein was designed, expressed, and then assembled to the glutathione self-assembled gold surface. The protein assembly was confirmed through enzyme binding assay and enzyme immunoassay.

Calmodulin (CaM), a calcium ion sensitive protein, was conjugated with dioctadecyldimethylammonium bromide and subsequently assembled into a monolayer at the air-water interface using the LB method. The lipid-conjugated calmodulin (LCC) retains its calcium sensitivity, determined from the changes in the area-pressure isotherm of the monolayer obtained at(More)
