Solid-supported membrane biosensors

摘要

The new membrane biosensors consist of a solid A as a support, a lipid bilayer B as a membrane, spacers C incorporated between A and B and a receptor D embedded in the lipid bilayer. The new membrane biosensors are characterized in particular by their spacer C, which consists of a molecule of ethanolamine which forms an ester bond to the phosphatide group of the lipid bilayer B, an oligopeptide in helical or pleated sheet structure formed from 4-20 C2-C10- alpha -amino acids and a reactive group which enters into a chemical or physicochemical bond with the support A.
