Abstract

A nanoscale laser induced fluorescence (nano-LIF) imaging was proposed by using the fluorescent dye and the evanescent wave. The present study focused on the measurement of zeta-potential distribution at the microchannel wall, which governs an electroosmotic flow field. A mixing flow field was formed by two-kinds of solution at different Na+ concentration in a T-shaped microchannel. The zeta-potential distribution obtained from nano-LIF is quantitatively related to the transport of Na+ in the flow field.
