Brownian Dynamics Simulation of a Polymer Model for Artificial Molecular Motors
Abstract
In this communication we report the results of numerical simulations for artificial biomimetic molecular motors. The theoretical models used in the simulations are based on generic ratchet models for the mechanisms that underlie force generation in actual biological motors. The expectation is, that when the motors are realized experimentally, they will be able to perform useful tasks. Two separate projects are envisaged: 1. An artificial molecular motor modeled by a single polyelectrolyte and based on the physics of a DNA molecule. 2. A model for a coupled motor consisting of many such polyelectrolytes attached to a larger object, e.g. a glass fiber. The driving force for the artificial motors is provided by a patterned assymetric electrode in flashing ratchet mode representing a Brownian motor. A Brownian dynamics algorithm is used and results for the kinetic behavior of the artificial motors will be presented.
