WebFigure 3(b) shows the chronoamperometry curve of functionalized electrode with HRP at a fixed potential of 350 mV after H 2 O 2 injections. The current increases with increasing H 2 O 2 concentration which agrees with result shown in Figure 3(a). The addition of the hydrogen peroxide to the buffer solution increases the steady state current. WebChronoamperometry experiments are most commonly either single potential step, in which only the current resulting from the forward step as described above is recorded, or double potential step, in which the potential is returned to a final value (E f) following a time …
