Figure 4. a) Transfer characteristics (VDS = 0.05 V) of a SGGT with Pt gate electrode measured in PBS solution before and after the addition of dopamine with the concentration of 1 μM. b) Channel current response of the SGGT to additions of dopamine with different concentrations. VDS = 0.05 V, VG = 0.7 V. Inset: the change of effective gate voltage (Δ VGeff) for different dopamine concentrations.
