Figure 3 Flow injection analysis of 1 nM of a9.5 kilobase oligonucleotide at a Cu electrode with sinusoidal voltammetry. Upper graph shows the signal at different frequencies after Fourier transform of the voltammograms for single-stranded (ss) and double-stranded (ds) DNA. Lower trace shows a flow injection trace for the ds DNA at the sixth
