Nanopore-Based DNA Analysis via Graphene Electrodes

Figure 2

((a)–(d)) The transmission spectra of adenosine, cytidine, guanosine, and thymidine under the same bias voltage of 2.4 V ( ± 1 . 2  V on each electrodes, which determine the “window” of the transmission), respectively. Because the transmission coefficient of each nucleotide, as well as the tunneling current, is quite different from each other, nearly one or two orders; to hold the maximums of four diagrams the same, we use different scale in each figure.
