From: Selective detection of dopamine with an all PEDOT:PSS Organic Electrochemical Transistor

Trans-conductance curves recorded (A) in a solution containing AA (1 mM), DA (0.1 mM) and UA (0.5 mM) at different scan rates and (B) in a solution containing dopamine at different concentrations plus 0.1 mM uric acid and 0.5 mM ascorbic acid (fixed concentrations) at 0.002 V s−1.
