FSCV study of 3D-printed nanoelectrodes. a) Background current. b) Background-subtracted current of 10 μM dopamine. c) Dopamine current is linear with scan rate (R2 = 0.9952, n = 3). d) Dopamine current when concentration is varied from 10 μM to 150 μM (n = 3). e) Dopamine current is linear with concentration up to 50 μM (R2 = 0.9947), f) Stability test. 10 μM dopamine was injected every 0.5 h for 5 h (n = 3).
