Figure 7

The differential pulse voltammetry (DPV) responses of the AFP nanoprobes in pH 6.5 PBS solution with different concentrations of AFP (0.0, 0.1, 0.5, 1.0, 5.0, 10, 50, 100, and 200 ng·mL−1 from a to k ) at 25 °C for 20 min. Inset: the relationship between log of DPV current signal towards log of different AFP concentrations.
