FIGURE 2.
Current, at a bias of 0.1 V, as a function of time for poly(A)15, as (a) it is propagating through a pore with two electrodes without a stabilizing field, and (b) when the driving field is turned off at a time (indicated by the dashed line in a) while a base is aligned in between the electrode pair. Solid vertical line in panel a indicates the time at which the DNA starts propagating through the pore. The transverse electric field is included in the simulations for panel b. Δt represents a finite inverse bandwidth.
