Characteristics of platinized nanoelectrode. A Current–voltage characteristic in 1 mM FcMeOH in PBS. Scan rate 400 mV s−1. B Platinized nanoelectrode calibration. Chronoamperogram of a platinized electrode at + 800 mV, measured in solutions with different concentrations of hydrogen peroxide. The vertical lines in the graph indicate the change in solution concentration. Concentration is shown in micromoles. C Calibration curve (current vs H2O2 concentration at + 800 mV (vs. Ag/AgCl)) showing good linear response D Calibration curve (current vs NO2− concentration at + 800 mV (vs. Ag/AgCl)) showing good linear response
