Electrokinectic effects in closed microchannels

Abstract

In the field of BioMEMS, electroosmosis phenomena have always been an integral part of its research due to its abundant applications. For instance, electroosmosis has been utilized as a powerful pumping means to precisely transport and manipulate liquid samples in microfluidic devices used for chemical analyses and biomedical diagnoses. Compared with conventional mechanical pumping modes, the electroosmosis-based pumping has numerous advantages including ease of fabrication and control, no movable mechanical parts, and high repeatability and reliability.
