Amperometric diagram. The amperometric current responses of the PEDOT-PtNPs/SPC electrode in response to various H2O2 concentrations, ranging from 0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0, 5.5 to 6 mM, in 0.1 M PBS solution (pH 7.4) at the applied potential of −0.6 V (vs. Ag/AgCl/KCl saturated). The inset shows the calibration curve for H2O2.
