Abstract
Recent designs in microfluidic devices extend common separation concepts by exploiting new non linear phenomena for molecular dynamics on a length scale of 10 microns and below, giving rise to novel manipulation tools and non-intuitive phenomena for microseparations. A rather paradoxical and new migration phenomenon termed absolute negative mobility (ANM) using thermal fluctuations in a nonequilibrium environment generates average motion of particles in the direction opposite to an applied static force [1]. Here, we propose how ANM can be accelerated in order to improve maximum velocities for future applications such as purification or sorting of colloidal particles, cells and cell compounds.
