摘要
Using periodic boundary conditions and external electric potential field, we have simulated an ion current flow through a flexible nanopore using cations and an explicit extended simple point charge (SPC/E) water with molecular dynamics simulation. The simulation voltages range goes beyond the usual ionic channel measurements (1V) and yields useful information about density profiles, current density distribution and current-voltage (I-V) characteristics.
