Segregation of ring polyelectrolytes in nano-channel

Abstract:
A segregation process of two ring polyions in the confined environment, represented by a tight nanopore, has been investigated. The study was performed by means of the nonequilibrium Monte Carlo method on the lattice. The ring geometry and thermodynamics, in categories of conformational entropy and electrostatic interactions in the course of segregation, have been analyzed. The influence of the polymer molecular weight and the radius of the nanochannel on the segregation process have been examined. The results have been discussed in terms of scaling laws describing the velocity of segregation vs. the molecular weight of polymer and the nanochannel width.
