    A new concept for liquid manipulation has been developed and implemented in surface micromachined fluid channels. It is based on the surface tension directed injection of a gas into the liquid flow through micron sized holes in the microchannel wall. The injected gas is directed to an exhaust by a crosssectional asymmetry of the microchannel, and thereby moves minute liquid volumes. Successful pumping experiments have been performed with single stroke volumes in the range of 10-40 pL at frequencies around 1 Hz.
