- Recent experiments of translocation of double stranded DNA through nanopores M. Wanunu
textitet al. Nature Nanotech. 5, 160 (2010) reveal that the DNA capture rate can be significantly
influenced by a salt gradient across the pore. We show that osmotic flow combined with electrophoretic effects can quantitatively explain the experimental data on the salt-gradient dependence of the capture rate.
