Abstract

The translocation dynamics of polymers though nanopores driven by external fields is a far-from-equilibrium process, which can be understood based on the tension propagation (TP) theory of Sakaue [1]. In particular, the coarse grained Brownian Dynamics TP theory within the iso-flux (IFTP) assumption [2] allows a self-consistent derivation of analytic equations of motion for the dynamics, including an explicit form for the chain length dependence of the average translocation time [3]. In this talk I will discuss the fundamentals of the IFTP theory and its various applications theory to translocation dynamics of long semi-flexible [4] and end-pulled polymer chains [5]. Time permitting I will also discuss recent works trying to elucidate the role of hydrodynamics and electrostatic interactions on translocation of rod-like molecules in finite and infinite cylindrical nanopores [6].
