a CV curves of the APS-Au NPs (Si:Au = 100:0.1 (a), 100:1 (b), and 100:10 (c)) electrodes recorded for 250 μM of hydrazine at a scan rate of 50 mV s−1. b CV curves of the APS-Au NPs (Si:Au = 100:1) electrode with different scan rates of 10 (a), 20 (b), 50 (c), 75 (d), 100 (e), 125 (f), and 150 (g) mV s−1 for 250 μM hydrazine. Inset: the plot of anodic peak current against square root of scan rate. c CV curves of the APS-Au NPs (Si:Au = 100:1) electrode recorded for 250 (a), 500 (b), 750 (c), 1000 (d), 1250 (e), and 1500 μM (f) of hydrazine at 50 mV s−1. Electrolyte, 0.1 M PB (pH 7.2). d The corresponding calibration plot
