From: A wireless, implantable optoelectrochemical probe for optogenetic stimulation and dopamine detection
a Cyclic voltammetry (CV). b Differential pulse voltammetry (DPV). c Chronoamperometry (CA). d Calibration curve: linear relationship between response currents and dopamine (DA) concentrations (0.1–10 μM). e Fast scan cyclic voltammetry (FSCV). All the experiments are performed in HCl solutions (pH = 4.0) with varied dopamine concentrations at room temperature, with a saturated Ag/AgCl electrode as the reference and a Pt sheet as the counter electrode
