Figure 5
Cyclic voltammetric responses of (a) the complete (cyan curve) or incomplete (black, red, green and blue curves) MCMA in the electrolyte containing 20 μM thionine and 6 mM H2O2 and (b) the MCMA fabricated with different amounts of cells. Other conditions were the same as those in (a). (c) The relationship between the peak current and the cell numbers. The dots represent the currents of the corresponding cyclic voltammogram at −0.25 V. (d) The current response for the MCMA with 1 × 106 cells over three cycles. The top dots represent responsive currents, whereas the bottom dots represent background currents. All dots were taken from the corresponding cyclic voltammogram at −0.25 V.
