Enzyme-based bilayer conducting polymer electrodes consisting of polymetallophthalocyanines and polypyrrole-glucose oxidase thin films.
Bilayer conducting polymer electrodes, which consist of a polymetallophthalocyanine (PMePc) and polypyrrole incorporating glucose oxidase (PPy-GOx), were prepared on the glassy-carbon electrode by the successive electrochemical deposition of two different polymers. The bilayer film electrodes showed catalytic behavior, which included an enhanced amperometric response current with the substrate and a significantly shifted oxidation potential (approximately 700 mV) of the response current. The bilayer electrodes also showed a fast response time and good stability with the substrate. A bilayer microelectrode, which was prepared by using both PCuPc and PPy-GOx polymer films, also showed a good amperometric response with the substrate.
