Original Kurzfassung:
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.
