Electrode components and their effects on the electrochemical performance. There are four electrode conditions: PPy only, PPy plus AuNP and with 0.05, 0.005 and 0 wt% Gox. The Faradic current of 1 mM FCA was obtained at 600 mV. The inset shows the CV curves recorded in FCA supplemented PBS with PCNTA sensors containing PPy only (a) and PPy plus AuNP and 0.005 wt% Gox. Voltage scanned from −600 to 600 mV at 100 mV/s.
