Concentration effect (from 30 to 100 nu/ mL − CA15-3) on biosensor signals: (A) DPV plots and (B) Calibration plot of the biosensor. (C) and (D) calibration plot of the CA15-3 biosensor in the presence of healthy serum. (C) The obtained biosensor DPV signals and (D) the plotted peak height vs. concentration. Each experiment 5 times repeated (n = 5).
