A novel optical measurement technique has been developed to investigate diffusion and transport phenomena at the chemical reaction interface in Lab-on-a-chip and micro-TAS. A micro-PIV technique was applied to measure velocity fields near the interface comprising pure water and oleic acid. Velocity and temperature at the interface were measured by using a caged-fluorescent dye. Velocity was obtained from the displacement of a peak value of the fluorescent intensity, while temperature was calculated by diffusivity of the dye. Results obtained from the present work will contribute to development of the next generation of microfluidic devices.
