Polymer translocation has been one of challenging research topics in polymer physics. Despite great progresses made in previous studies
many essential problems remain unsolved. This review has expounded some major advances in different aspects of translocation
such as capture process
critical flux
conformational transition
and translocation time.
The translocation of a polymer through a pore that is much smaller than its size is a fundamental and actively researched topic in polymer physics. An understanding of the principles governing polymer translocation provides important guidance for various practical applications
such as the separation and purification of polymers
nanopore-based single-molecule deoxyribonucleic acid/ribonucleic acid(DNA/RNA) sequencing
transmembrane transport of DNA or RNA
and infection of bacterial cells by bacteriophages. The past several decades have seen great progresses on the study of polymer translocation. Here we present an overview of theoretical
experimental
and simulational stduies on polymer translocation
focusing on the roles played by several important factors
including initial polymer conformations
external fields
polymer topology and architectures
and confinement degree. We highlight the physical mechanisms of different types of polymer translocations
and the main controversies about the basic rules of translocation dynamics. We compare and contrast the behaviors of force-induced versus flow-induced translocations and the effects of unknotted versus knotted polymers. Finally
we mention several opportunities and challenges in the study of polymer translocation.
