From: Active translocation of a semiflexible polymer assisted by an ATP-based molecular motor

Section of the polymer translocating through a nanopore in 3d. The pore has a square section of width L H and its length is L M . Inside the pore it is present a driving force in the x-direction, which pushes the polymer toward the trans side of the membrane. The walls of the membrane repulse uniformly the chain inside a characteristic distance σ.
