Figure 4. (a) Cyclic voltammograms of Nafion/Au electrode(solid line) and Nafion/ZnO/Au electrode (dotted line) in 0.01M PBS (PH = 7.4) at scan rate of 50 mv/s. (b) CV curves of the Nafion/Gox/ZnO/Au electrode in the 0.01M PBS (PH = 7.4) without (solid line) and with (dotted line) of 3mM glucose.

Figure 5. Cyclic voltammograms for a Nafion/ZnO/Gold electrode, withouht(solid line) and with (dotted line) with 1 mM N_2H_4 in 0.1M phosphate buffer (PH=6.6). The scan rate was 100mV/s
