Using channel depth to isolate and control flow in a micro free-flow electrophoresis device.


A multiple-depth micro free-flow electrophoresis chip (mu-FFE) has been fabricated with a 20-microm-deep separation channel and 78-microm-deep electrode channels. Due to the difference in channel heights, the linear velocity of buffer in the electrode channels is approximately 15 times that of the buffer in the separation channel.
