This chapter describes a new type of micro/nano fluidic mixer based on non-equilibrium electrokinetics. The device is fabricated with two-step reactive ion etching, one for nanochannels and one for microchannels. Mixing is achieved by strong vortex structures formed near the micro/nano channel interface. The micro/nano fluidic mixer is expected to be beneficial in the development of many lab-on-a-chip systems, since it is simple in its design with minimal fabrication complications read more ...
