Title:Simultaneous Particle Separation with AC-Driven Electroosmotic MicropumpsAuthor(s):Wolfgang Hilber, Bernhard Weiss, Ahmad Saeed, Thomas Lederer, Bernhard JakobyAbstract:In this contribution we present a novel mechanism of particle separation in microchannels, based on the tunable ratio of viscous drag, inertial and dielectrophoretic forces. The latter are induced by stepped electrode arrays in the channel, which, driven by AC voltages, enable so-called 3D-AC-electro-osmotic pumping (3D-ACEO). By adjusting the operation parameters of the micropump, particle mixtures can simultaneously be pumped and separated with respect to density.Journal:International Journal of Heat and TechnologyEditor(s):Edizioni EtsISSN:0392-8764Page Reference:page 83-87, 5 page(s)Publishing:1/2010Volume:28Number:1-2010
