Cyclic voltammetry. The dependences of adenine peak height on ln of scan rates (50, 100, 200, 400, 600 and 800 mV/s) measured at (A) microcarbon, (B) nanocarbon and (C) nanocarbon II. In insets: dependencies of adenine peak potentials on ln of scan rate. Square wave voltammetry. SW voltammograms of (D) single strand oligonucleotide influenza (13 μg/mL), and (E) double strand genomic DNA (15 μg/mL). In insets: signals of all nucleic acid bases after baseline correction and smoothing of raw data.
