Fig. 5.(A) DP and (B) SW voltammograms for various TB concentrations: (a) 0, (b) 0.99, (c) 4.76, (d) 9.09, (e) 16.7, (f) 28.6, (g) 37.5, (h) 44.4, (i) 50.0 and (j)54.5μMin0.1MH2SO4on the miniaturized BDDE. The DPV parameters: modulation amplitude of 100 mV, modulation time of 100 ms and scan rate of 10 mV/s. TheSWV parameters: amplitude of 50 mV, frequency of 10 Hz and scan rate of 250 mV/s. The corresponding calibration curves are displayed in the insets.
