Active control of particle position by boundary slip in inertial microfluidics

A scheme is presented to actively control particulate position in inertial microfluidics. The unilateral slip boundary applied regulate the velocity distribution of flow field microchannel, thus vertical equilibrium particle can be changed with length. Three kinds typical particles, namely circular, elliptical, and rectangular, are simulated. results demonstrate that positions manipulated within 40% channel width. If adjusted by some technique, such as electrowetting, then real-time achieved.
