Technical Examples

Apparatus and methods according to the present invention preferably utilize electroosmotic pumps in fluid handling and field sampling applications. The electroosmotic pumps used in these applications are capable of generating high pressure and flow without moving mechanical parts and the associated generation of unacceptable electrical and acoustic noise, as well as the associated reduction in reliability. Having multiple small flow channels in parallel provides both a high flow rate and high pressure in liquid handling. These electroosmotic pumps are fabricated with materials and structures that improve performance, efficiency, and reduce weight and manufacturing cost relative to presently available micropumps. These electroosmotic pumps also allow for recapture of evolved gases and deposited materials, which may provide for long-term closed-loop operation. Apparatus and methods according to the present invention also allow active regulation of the fluid handling and field sampling devices through electrical control of the flow through the pump. Electroosmotic pumping enables precise dispensing of samples to form genetic, proteomic, or small molecule arrays. A fluid sensor which can be optical, capacitive or other type of electrical sensor is integrated with the electroosmotic pump for measuring liquid levels in liquid drawing and dispensing operations.
