We have been studied the electrochemical immunoassay with two electron-conducting redox polymers, PAA-AMP-[Os(dme-bpy)2Cl]+/2+, polyacryl acid-amino methyl pyridine (PAA-AMP) partially complex with [Os(dme-bpy)2Cl]+/2+ and PVI-[Os(dme-bpy)2Cl]+/2+, a poly(N-vinylimidazole) (PVI) partially complexed with [Os(dme-bpy)2Cl]+/2+,(dme-bpy = 4,4’-dimethyl-2,2’-bipyridine), were electrodeposited on the screen printed carbon electrodes (SPEs) and thiol-modified gold electrodes. The electrical signals were amplified by HRP which is electrically “wired” by two redox polymer films, converting the films into an electrocatalyst for the two-electron reduction of H2O2 to water. The resulting catalytical current was linearly related with the concentration of anti-lgG-HRP on lgG-modified electrodes. A study of the competitive assay with different species between rabbit and mouse indicated that the electrochemical immunoassay offer the development of cheap, miniature devices capable of performing rapid immunoassays.
