Abstract
A new measurement technique for ion velocity and diffusivity in the vicinity of interface is proposed for investigation of transport phenomena near the wall surface. This technique, which is called evanescent wave molecular tagging, utilizes caged fluorescent dye and evanescent wave illumination. Evanescent wave molecular tagging was performed in stationary flow and electroosmotic flow, and compared to molecular tagging with epi-fluorescent illumination. The ion diffusion near the wall surface can be also affected by the velocity gradient of the flow.
