(a) Differential pulse voltammogram of 0.1 M KCl without BOS using PGE/Au-NPs electrode with scan rate of 50 mV/s. (b) Differential pulse voltammograms of BOS at different concentrations in the range of (2.5 × 10–7–2.5 × 10–5 M) BOS using PGE/Au-NPs electrode with scan rate of 50 mV/s, showing anodic peak at 0.975 V.
