FSCV of dopamine. (A) Applied potential waveform using –0.4 V holding potential, +1.3 V switching potential, 400 V/s scan rate, and 10 Hz repetition rate. (B) Examples background currents: blank (PBS pH 7.4) (black) and buffer with 1 μM dopamine (red). Dashed boxes emphasize the difference between them. (C) Background-subtracted CV of 1 μM dopamine. (D) Three-dimensional current-potential-time plot and (E) Conventional false color plot with anodic peak current-time trace of 5-s bolus injection of 1 μM dopamine.
