The development of microfluidic separation technologies is one of the major issues in the area of lab-on-a-chip and micro total analysis system. However, previously reported passive methods for particle separation cannot separate microparticles without the aids of sheath flows and complex channel networks. In this presentation, separation and sorting of microspheres, including DNAs, blood cells, and mammalian cells, were demonstrated by using a novel microfluidic mechanism, "hydrophoresis", which uses slanted or anisotropic obstacles to induce hydrodynamic interaction between the obstacles and the particles subjected to rotational flows induced by the obstacles. The equilibrium positions of the particles by the hydrodynamic interactions depend on their size. Continuous separation and focusing of micro- and nano-particles were also achieved using a contraction-expansion array microchannel, demonstrating the potential of microfluidic techniques in a biochemical, clinical, and environmental field with high-throughput, low-cost and continuous separation.
