Electrochemical cleaning protocol on gold coated cantilever in 50 mM KClO
. Cyclic voltammogram in 50 mM KClO4 (vs. Ag/AgCl (sat. KCl)). A, the standard gold spectra is shown at 20 mV/sec indicating a clean gold surface. B, a chloride contaminated surface is electrochemically cleaned. After six full potential sweeps, the chloride peaks vanish and a clear distinct gold reduction peak is observed.
