This micropump developed by MIT researchers allows high speed flows through microchannels with an input of only a few volts of electricity, making it possible to create portable "lab on a chip" devices.
The three-dimensional, alternating current electro-osmotic pump consists of interdigitated stepped gold microelectrodes on a glass substrate.

MIT research scientist Rutledge Ellis-Behnke, left, and Professor Gerald Schneider bracket a monitor showing a transected liver after it has been treated with a liquid solution containing peptides. The peptides self-assemble into a gel that essentially seals over the wound. The two developed the technique with MIT colleagues and researchers at the University of Hong Kong.
