  • Title: Simulations of polyelectrolyte dynamics in an externally applied electric field in confined geometry.
    Author: Nedelcu S, Sommer JU.
    Journal: J Chem Phys; 2010 Dec 28; 133(24):244902. PubMed ID: 21198005.
    Abstract:
    We consider the dynamics of charged polymers in free solution in a slit geometry under the influence of an electrical field, applied at an angle to the plane parallel walls of the confinement. The simulations are carried out using the Brownian dynamics method with explicit counterions and implicit hydrodynamics. The hydrodynamic interactions between all the particles and the plane parallel walls are taken into account using a diffusion matrix which depends on slit geometry and the actual polyelectrolyte-solute conformations. We observe a selective transport of the charged polymers, as a function of the degree of polymerization and slit height.
