Fig. 5. (A) ChAs of prepared immunosensor in various concentrations of SNCA (4, 8, 16, 32, and 64 ng mL−1) in 0.01 M [Fe(CN)6]3−/4−/KCl solution as an electrochemical probe at E = 0.6 V, duration time = 100 s and (B) calibration curve of current intensity changes against logarithm of SNCA concentration. (C) Nyquist plots for electrochemical impedance measurements of different concentrations of SNCA (n = 4, Sd = 3.8).
