An Active Micromixer Based on Non-equilibrium Electrokinetics for Lab-on-a-Chip Systems
from: Lab-on-a-Chip Technology (Vol. 1): Fabrication and Microfluidics (Edited by: Keith E. Herold and Avraham Rasooly). Caister Academic Press, U.K. (2009)
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 ...
