Abstract
Abstract The present invention relates to a potential-causing membrane for use in immunosensors, which comprises an electrically-conductive film being prepared by electrolytic polymerization of an electrolytic polymerizable monomer, having at least one functional group, such as NH2 group and COOH group, capable of binding an antigen or an antibody, and binding an antigen or an antibody through the functional group onto the film. Examples of the monomer include 3-bromopyrrole, 3,4-dichlorothiophene, 3-bromofuran, 0-chlorophenol and m-bromo-aniline.
