L-DOPA fouls bare carbon-fiber microelectrodes in vitro. Normalized electrode response to 1 µM DA in the absence (black) and presence (grey) of (A) 1 µM or (B) 50 µM L-DOPA in the running buffer of the flow-injection apparatus. Sensitivity was significantly attenuated in the presence of 50 µM L-DOPA (n = 6, paired t- test, *** p<0.001).
