A simultaneous measurement technique of the near-wall electroosmotic velocity and the wall zeta-potential was developed by using the evanescent wave. Nano particle image velocimetry (nano-PIV) with submicron fluorescent particles and nanoscale laser induced fluorescence (nano-LIF) with fluorescent dye were used for the velocity and zeta-potential measurement, respectively. The images of particles (red fluorescence) and dye (green fluorescence) were captured by a 3CCD camera. The present study focused on the vicinity of the microchannel wall with uniform zeta-potential.
