Enzyme-free electroreduction of hydrogen peroxide at polypyrrole/graphene/au microelectrode based on three-electrode-system array
This work reported a one-step electrodeposition to fabricate a graphene nanosheets doped polypyrrole modified gold (PPy/GENS/Au) electrode at the on-chip three-electrode-system electrochemical sensor array. The PPy/GENS/Au electrode exhibited excellent electrochemical properties of large current response, good reproducibility and stability. When applied for the detection of hydrogen peroxide (H2O2), this proposed sensor carry out a rapid, direct and selective determination of H2O2 with the linear range from 1 to 10mM (R-square=0.9914) and a sensitivity of about 32 μA mM-1cm-2. The simple and low-cost construction of PPy/GENS/Au electrode shows a great promise to fabricate mass-produced nano-platform for potential application of biosensing analysis in a lab-on-a-chip system.
