In systems possessing spatial or dynamical symmetry breaking, Brownian motion combined
with unbiased external input signals, deterministic and random alike, can assist directed …

Transport phenomena in spatially periodic systems far from thermal equilibrium are
considered. The main emphasis is put on directed transport in so-called Brownian motors …

A great challenge for the burgeoning field of nanotechnology is the design and construction
of microscopic motors that can use input energy to drive directed motion in the face of …

The dramatic recent advances in molecular biology, which have opened a new era in
medicine and biotechnology, rely on improved techniques to study large molecules …

We use the mesoscopic nonequilibrium thermodynamics theory to derive the general kinetic
equation of a system in the presence of potential barriers. The result is applied to a …

Brownian ratchets use a time-varying asymmetric potential that can be applied to separate
diffusing particles or molecules. A new type of Brownian ratchet, a geometrical Brownian …

In a two-dimensional periodic but asymmetric environment, a Brownian particle that is driven
in one direction by a potential gradient will also drift in the orthogonal direction at a rate that …

Picking up at the conclusion of Viovy's review of the physics of gel electrophoresis [J.-L.
Viovy, Rev. Mod. Phys. 72, 813 (2000) 10.1103/RevModPhys. 72.813], this review …

We have micromachined a silicon-chip device that transports DNA with a Brownian ratchet
that rectifies the Brownian motion of microscopic particles. Transport properties for a DNA 50 …

The design of analogue electronic experiments to investigate phenomena in nonlinear
dynamics, especially stochastic phenomena, is described in practical terms. The advantages …
