摘要

Abstract

We investigate the statistics of polymer capture by a nanopore using Brownian dynamics simulations. It is found that when the velocity flux is greater than a critical velocity flux

the capture picture is a random selection process

otherwise it tends to a statistical process governed by energetic considerations. In addition

the chain ends capture probability decreases as the chain length increases and satisfies a power-law scaling of P
