Comparison of a bare (solid line) and a SWCNT forest modified (dotted line) disk carbon-fiber microelectrode for the detection of 1 μM dopamine. A. The modified electrode exhibits a 15-fold higher background current than the bare electrode. The inset is the background CV for the bare electrode. B. The oxidation current of 1 μM dopamine is 30-fold higher at the SWCNT forest electrode. The inset shows the dopamine CV for the bare electrode. C. Current vs. time responses for a flow injection analysis experiment. The responses were averaged from 10 electrodes each (error bars are not shown for clarity). The inset shows traces normalized to the same peak height for better comparison in peak shapes.
