Abstract:
     The compound conductive polymer film used as biosensor fixing carrier is prepared through mixing protein solution and pyrrole in certain ratio, electric polymerization inside proper buffer solution in a three electrode system, oxidation at some potential for certain time and reduction at some other potential for certain time to obtain compound conductive polymer film. Or, it may be prepared through mixing pyrrole with buffering solution, electric polymerization in a three electrode system, oxidation at some potential for certain time and adsorption in protein solution at some other potential for certain time to obtain laminated compound conductive polymer film. The compound conductive polymer film of the present invention is used as bioactive matter fixing carrier in preparing biosensor with fast response, wide linear response range, long service life and excellent repeatability and high selectivity.
