We present electric field-mediated transport, focusing, and separation of microparticles in curved microchannels. Due to the curvature-induced electric field non-uniformity, particles experience negative dielectrophoresis when they migrate electrokinetically through a curved microchannel. This cross-stream particle motion is utilized to either focus particles into a tight stream near the outer wall, or separate particles by size to dissimilar streams in spiral microchannels.
