Recent years have seen an explosion of interest in the field of microfluidics. Many possible applications exist for low cost, portable fluidic systems; examples include drug delivery devices, chemical reactors, and DNA sequencers. In many of these systems, the thorough mixing of small amounts of two or more fluids will be required. While it may at first seem that diffusion will be sufficient to quickly mix fluids in a sub-millimeter scale channel, this is often not the case. To meet this need, a new mixing process for...
