We consider the translocation of a one-dimensional polymer through a pore channel helped by a motor driven by a dichotomous noise with time exponential correlation. We are interested in the study of the translocation time, mean velocity and stall force of the system as a function of the mean driving frequency. We find a monotonic translocation time, in contrast with the mean velocity which shows a pronounced maximum at a given frequency. Interestingly, the stall force shows a nonmonotonic… 

Translocation dynamics of a short polymer driven by an oscillating force.

The mean first translocation time of the center of inertia of polymers shows a nonmonotonic behavior, with a minimum, as a function of the number of the monomers, which represents the evidence of the resonant activation phenomenon in the dynamics of polymer translocation.

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

The assisted translocation of a polymer across a membrane nanopore, inside which a molecular motor exerts a force fuelled by the hydrolysis of ATP molecules, shows a Michaelis-Menten translocation velocity that depends on the chain flexibility.

Force spectroscopy analysis in polymer translocation

This paper reports the force spectroscopy analysis of a polymer that translocates from one side of a membrane to the other side through an extended pore, pulled by a cantilever that moves with

Translocation through environments with time dependent mobility.

This work constructs general diffusive and non-diffusive frequency response of the gain in translocation time for a single particle in changing environments and looks at some specific variations.

Polymer translocation under time-dependent driving forces: resonant activation induced by attractive polymer-pore interactions.

It is found that the nature of the interaction fundamentally affects the translocation dynamics of polymers under time-dependent driving forces, and that the attractive pore case can be a minimum at the optimal frequency of the force, the so-called resonant activation.

Entropic noises-induced resonance in a geometrically confined system

We consider the motion of Brownian particles through a narrow tube of varying cross-section in a geometrically confined system subjected to a sinusoidal oscillating force. The varying cross-section

Reaction–diffusion systems with fluctuating diffusivity; spatio-temporal chaos and phase separation

The homogeneous stable state of a one-component reaction–diffusion system with positive diffusivity always remains stable by diffusion. We have shown that dichotomously fluctuating diffusivity leads

Noise driven translocation of short polymers in crowded solutions

In this work we study the noise induced effects on the dynamics of short polymers crossing a potential barrier, in the presence of a metastable state. An improved version of the Rouse model for a

Resonant activation in polymer translocation: new insights into the escape dynamics of molecules driven by an oscillating field

The mean first translocation time of the polymer centre of inertia shows a minimum as a function of the frequency of the oscillating forcing field, which represents the first evidence of the resonant activation behaviour in the dynamics of polymer translocation.

Noise Effects in Polymer Dynamics

A two-dimensional stochastic version of the Rouse model for a flexible polymer has been adopted to mimic the molecular dynamics and to take into account the interactions between adjacent monomers.

Single-polymer Brownian motor: a simulation study.

It is found that the polymer motor performs qualitatively better than a single particle in a flashing ratchet: with increasing N, the polymer loses velocity much more slowly than expected in the absence of internal degrees of freedom, and the motor stall force increases linearly with N.

Mechanical coupling in flashing ratchets.

This work considers the transport of rigid objects with internal structure in a flashing ratchet potential by investigating the overdamped behavior of a rodlike chain of evenly spaced point particles and may provide a route to simple, coarse-grained models of molecular motor transport that incorporate an object's size and rotational degrees of freedom into the mechanism of transport.

Two-state flashing molecular pump

Here we study a pumping device capable of maintaining a density gradient and a flux of particles across a membrane. Its driving mechanism is based on the flashing ratchet effect powered by the random

A Theory of the Linear Viscoelastic Properties of Dilute Solutions of Coiling Polymers

The necessary coordination of the motions of different parts of a polymer molecule is made the basis of a theory of the linear viscoelastic properties of dilute solutions of coiling polymers. This is

Fluctuation-driven molecular transport through an asymmetric membrane channel.

It is argued that channel asymmetry in the presence of nonequilibrium fluctuations, fueled by the cell's metabolism as observed recently, can dramatically influence the transport through such channels by a ratchetlike mechanism.


A screw model is introduced which may describe translocation of DNA duplexes through artificial nanopores of the proper diameter in a qualitatively correct way and is capable of qualitatively explaining chemical-to-mechanical energy conversion in DNA–protein molecular machines via symmetry breaking inDNA–protein friction.
