Try out PMC Labs and tell us what you think. Learn More. In this work, we report coarse-grained molecular dynamics simulations of the translocation of nanoparticles through a cylindrical nanochannel coated with the polymer brush. The effects of the interparticle interaction and grafting density on the distribution and electrokinetic transport of nanoparticles are addressed in detail.

Method : Single-anonymous Revisions: 2 Screened for originality? Buy this article in print. It is found that chain stiffness plays an important role in topological polymer brushes, and there exists scaling laws for the radius of gyration against chain stiffness and topological feature, indicating that bending interaction is as important as topological constraint. An empirical finitely extensible nonlinear elastic force in terms of chain stiffness and topological features is also obtained by fitting related parameters.
