| Summary: | Fluid motion in most microfluidic systems is often achieved by electroosmotic (EO) flow due to its unique characteristics and advantages. This method allows controlled, high precision handling and pumping of small quantities of fluids through microchannels with the use of electric field. One of the characteristic parameter that governs the flow velocity is the Zeta potential. Zeta potential is the electrical potential developed at a surface which is placed in contact with a liquid due to the formation of the electrical double layer. It is difficult to be measured accurately. Current techniques to measure Zeta potential involve experiments that infer the Zeta potential indirectly, with assumptions and approximations that might induce inaccuracies. |
