Figure S2. The effect of ssDNA-Au electrode treated with TMPD only.

Figure S2 shows the CV curves of [Fe(CN)6]3−/[Fe(CN)6]4− recorded using ssDNA-Au electrode after treatment with 1 mM TMPD only at various time points. The nearly identical current responses over time showed that TMPD itself has little effect on [Fe(CN)6]3−/[Fe(CN)6]4− signal recovery.
