Abstract

The present study experimentally investigated the three-dimensional structure of electroosmotic microchannel flow with nonuniform zeta-potential. The effect of zeta-potential distribution at the wall on electroosmotic flow was evaluated quantitatively by the velocity measurement using spatially averaged time-resolved particle-tracking velocimetry (SAT-PTV). This paper reports the measurement using a straight microchannel comprised of glass and PDMS with the surface chemical modification.
