Title:Particle Separation Using AC-Driven Electro-Osmotic PumpsAuthor(s):Wolfgang Hilber, Bernhard Weiß, Ahmad Saeed, Roman Holly, Bernhard JakobyAbstract: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 inclined, 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 be pumped and separated simultaneously.Booktitle:Proceedings of Eurosensors XXIIISBN:978-3-00-025217-4Page Reference:page 1353, 1622 page(s)Publishing:2008
