摘      要：The translocation of a polymer through a pore that is much smaller than its size is a fundamental and actively researched topic in polymer *** 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 *** past several decades have seen great progresses on the study of polymer *** 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 *** highlight the physical mechanisms of different types of polymer translocations,and the main controversies about the basic rules of translocation *** compare and contrast the behaviors of force-induced versus flow-induced translocations and the effects of unknotted versus knotted ***,we mention several opportunities and challenges in the study of polymer translocation.
