(A) Calibration curve of the immunosensor for different concentrations of estradiol. (B) A comparison of amperometric responses of 10 ng·mL−1 estradiol with those of 100 ng·mL−1 different interfering species: (a) blank, (b) pyrogallolred, (c) naphthol, (d) fluorone black, (e) 1-(2-Pyridylazo)-2-naphthol and (f) diethylstilbestrol, amperometric response at−0.3 V vs. SCE with the addition of 100 μL 1.0 mmol·L−1 H2O2.
