(a) DPV curves of different concentrations of CC (0, 0.1, 0.15, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 1.0, 1.2 mM) in the presence of 0.2 mM RS using NCNTs (2 : 1)/GCE; (b) DPV curves of different concentrations of RS (0, 0.05, 0.1, 0.2, 0.4, 0.6, 0.8, 1.0, 1.2 mM) in the presence of 0.2 mM CC using NCNTs (2 : 1)/GCE; (c) the calibration plot shows oxidation peak currents as a function of CC and RS concentration.
