More Information
Summary:Reduction of dioxygen catalyzed by laccase was studied at poly(3,4-ethylenedioxythiophene) (PEDO) modified electrodes. PEDOT with laccase are directly fabricated on pt electrode by simple process. The cyclic voltammetry (CVs) has been used for the measurement of electroanalytical properties of analytes by means of modified electrodes. The GOx/MWCNTs modified electrode exhibited good catalytic activity towards glucose oxidation and the PEDOT-laccase/pt modified electrode exhibited good catalytic activity towards O2. The maximum power density was 102 μWcm−2. The stabilities of laccase, the reduction potentials and ratios of catalytic to background currents were compared. Efforts are underway to improve the interface transfer to achieve higher potential and current output.
