Polymer translocation through a nanopore in presence of attractive binding particles

ORAL

Abstract

We use Brownian dynamics simulation to study the translocation of a flexible linear polymer chain through a nanopore into a cell containing particles those bind reversibly to the chain. We study the role of these binding particles [1] by monitoring the mean first passage time, the diffusion of the center of mass, and the net force on the translocating chain as a function of the density of these particles and the strength of the attractive interaction. \newline [1] Roya Zandi,David Reguera, Joseph Rudnick and William M.
