GLAVEY, R. and SAVEL'EV, S., 2015. Rectification of Brownian particles with oscillating radii in asymmetric corrugated channels. Acta Physica Polonica A, 128(2), pp. 159-162.
Transport of a Brownian particle with an oscillating radius freely diffusing in an asymmetric corrugated channel was simulated over a range of driving forces for a series of temperatures and angular frequencies of radial oscillation. It was observed that there was a strong influence of self-oscillation frequency on the average particle velocity. This effect can be used to control rectification of biologically active particles as well as for their separation according to their activity, for instance in the separation of living and dead cells.
