Quantitative measurements of electrokinetically driven flow and pressure driven flow were performed by micro-resolution particle image velocimetry (micro-PIV) in a cross-junction microchannel and a right-angle microchannel, for further development of Lab-on-a-chip and μ-TAS. The objective of the present study was to control electrokinetivcally driven flow which is frequently utilized to transport and separate a very small amount of fluid in microchannels. Velocity profiles of electrokinetically driven flow were affected by the configuration of micorchannel and can be controlled by the applied electric field.
