MICROCHIP INTEGRATED MULTICHANNEL ELECTROOSMOTIC PUMPING SYSTEM

摘要

A microchip integrated microfabricated, microfluidic, multichannel, preferably electroosmotic pump. The pump (10) comprising a plurality of microchannels (12), which begin and end in common compartments (14, 16), complexed into an array. To effectuate efficient flow of fluid without the hindrance of backpressure, an electroosmotic pump of the invention is coupled to a single channel of a larger cross-section. A similar structure is also used in an electroosmotic valve, where samples are introduced into an analytical device.
