Curvature-Induced Dielectrophoresis, Fig. 1 Mechanism of curvature-induced dielectrophoresis (C-iDEP) in a microchannel turn of angle, 0, where the dielectro-phoretic particle motion, Udep. competes with the elec-trokinetic particle motion, Uek, leading to a cross-stream particle deflection. The background color represent the contour of electric field, E (short arrows indicate the direction) (The figure is adapted from Ref. [2] with permission)... [Pg.516]
