Cyclic voltammetry behavior of (a) 50 μM pyocyanin in PBS buffer at bare ITO, (b) three different concentrations of pyocyanin in PBS buffer at bare ITO, (c) three different concentrations opyocyanin in PBS buffer at Au NPs modified ITO, (d) 50 μM pyocyanin in PBS buffer at PANI/Au NPs modified ITO and (e) 50 μM pyocyanin in PBS buffer at PANI/ modified ITO. The scan rate was 50 mV/sec.
