The present invention generally provides a micropump that utilizes electroosmotic pumping of fluid in one channel or region to generate a pressure based flow of material in a connected channel, where the connected channel has substantially no electroosmotic flow generated. Such pumps have a variety of applications, and are particularly useful in those situations where the application for which the pump is to be used prohibits the application of electric fields to the channel in which fluid flow is desired, or where pressure based flow is particularly desirable.

1. A method of inducing pressure flow of fluid in a first microscale channel, comprising: providing a first fluid-filled channel segment that is fluidly coupled to a second fluid-filled channel segment; and inducing electroosmotic flow of a fluid in the second channel segment but not in the first channel segment, whereupon the electroosmotic flow in the second channel segment translates to pressure flow in the first channel segment.
