Mean-square end-to-end distances, $\langle L^2\rangle$, of ssDNA exposed to E_r in a nanochannel at various values of z potential and λ_D. Here $\langle L^2\rangle$ is normalized by the mean-square end-to-end distance, $\langle L_0^2\rangle$, in an equilibrated solution in the channel. Data are shown for the polymer lengths (a) N = 50 and (b) 5. To see this figure in color, go online.
