19/2/2020, · The relative standard deviation (,RSD,) of the five working electrodes were 2.4%. This result showed the accuracy and reproducibility of the designed immunosensors. The glassy carbon electrode exhibited good repeatability and stability after scanning 120 times in the range of −0.2 V S −1 –0.6 V S −1 in 5 mM [Fe(CN) 6] 3−/4− solution.

Calibration curves. The calibration curve for FA was linear (r 2 =0.9993) over the concentration range 2.11–2,160.64 ng/ml, and a regression equation of y=248.31x + 3.22 (where x is the peak area ratio and y is the concentration of analyte) was obtained. The detection limit, based on a signal-to-noise ratio of 3, was 0.34 ng/ml, and the quantitation limit was 1.44 ng/ml.
