Figure 3

Translocation of poly(dA) ssDNA through graphene nanopores. Number of permeated nucleotides (a) and the associated pulling force (b) during 40 ns simulation, as well as the pulling force during a single base permeation step (15–20 ns) (c) when ssDNA is pulled through 1.6 nm (red line) and 2.4 nm (blue line) diameter graphene nanopores at a constant velocity of 2 Å/ns. Insets in (c) show side and top views of the ssDNA–graphene nanopore complex at different stages of a single base permeation step.
