(a) CV curves of 1 mM [Fe(CN)6]3−/4− in 0.1 M PBS (pH 7.0) at a scan rate of 50 mV s−1 and (b) Nyquist plots of 10 mM [Fe(CN)6]3−/4− in 0.1 M KCl from 0.1 MHz to 0.1 Hz at ac amplitude of 5 mV under open-circuit potential conditions, obtained at the GC (1) and ERGO/GC (2) electrodes. Inset of (b) is the SEM image for the ERGO/GC electrode.
