摘要

Abstract

The translocation of a long passive polymer chain (polymer P) through a small pore pulled by an active polymer chain (polymer A) was studied

via

simulation. The results indicate that the translocation dynamics of polymer P is strongly correlated with the conformation state of polymer A during the translocation process

depending on the active force

and the rigidity

of polymer A. For the case

is very small (including

=0)

polymer A is nearly a random coil at small

and forms a stable spiral at large

. When

is small

it is very difficult for polymer A to pull polymer P through the pore

and the translocation time (

) is large. When

is large

is small

and the translocation dynamics is determined by a winch-driven mechanism

where the spiral of polymer A rotates synchronously

pulling polymer P through the pore and winding it sequentially around itself. When

is large

polymer A adopts a rod configuration

and the translocation of polymer P is controlled by the translation of the polymer A rod.
