Rapid mixing is essential on the micro-mixer in microfluidic systems. Mixing in micro-channel relies mainly on molecular diffusion due to the laminar flow at low Reynolds number. In the traditional micro-mixer, the mixing is processed in a long micro-channel flowing with. In this study, the mixing and the transport processes are separated by switching the electroosmosis flow sequentially in the simple T-junction micro-channel. The mixing is enhanced by inducing the micro-vortex at the T-junction by the oscillating electroosmosis flow.
