Modelling and Controlling Electro-Hydrodynamics in Nanopore Translocation Experiments — •Andreas J Meyer and Peter Reimann — Universität Bielefeld

The translocation of biopolymers through nanopores is dominated by several competing effects, namely electrostatic forces resulting from an applied voltage difference, system-intrinsic charges, and the hence induced velocity field of the buffer solution. Since comprehensive molecular-dynamics simulations of translocation processes are practically infeasible, modelling the acting forces demands an effective description of nanoscopic structures and physical parameters. We employ a continuum description via Poisson-Nernst-Planck and Stokes equations for conducting numerical experiments and finding optimized parameter sets or new analysis techniques.
