Fig. 5

a Spectral response of SPR mode versus different E2 concentrations; b variations of ΔIntensity with the concentration of E2 and logarithmic calibration plot; c linear range and corresponding calibration plot to detect E2. Inset: intensity fluctuation of a blank sample. The error bars correspond to the standard deviation of the data points in triplicate experiments.
