Abstract: The present invention discloses a microfluidic separating and transporting device, which utilizes free-energy gradient surfaces having micro/nano physical and chemical properties to drive and separate microfluids automatically. The device of the present invention comprises a platform having microchannels. The surfaces of the microchannels have surface energy gradient-inducing rare-to-dense microstructures. The rare-to-dense microstructures are formed in two regions; one is formed in the primary microchannel and used to transport microfluids, and the other is formed in the microfluid bifurcation region. When different microfluids flow through the microfluid bifurcation region, the microfluids will separate automatically to their own secondary microchannels according to the surface energy gradient. Thereby, droplets of different microfluids can be separated apart or split into diffluences.
