The present invention is generally directed to improved microfluidic devices(100), systems, and methods of using the same. In particular, the device and systems employ channels (408, 512) having, at least in part, depths that are varied to provide advantageous effects upon the flow rate of fluids in the channel. Typically, microscale channel (408, 512) has an aspect ratio(width/depth) less than or equal to about 1. Variation of the channel depth(408, 512) may be optimized depending upon the nature of the materials to be mixed. |
