Extended Data Fig. 2

CVs (scan rate = 10 mV·s-1) show the oxidation of dopamine with a peak of ca. +0.1 V vs a saturated silver/silver chloride (sat’d Ag/AgCl) electrode for low dopamine concentrations (20–200 mM). At higher concentrations (0.5–1 mM), dopamine oxidation peak shifts and a secondary oxidation reaction is observed. The lack of a reduction peak in the reverse scan shows that the oxidation reaction is irreversible.
