Recently, μ-TAS have been attracted constant attention. In the case of antigen-antibody reaction, concentration of particle effects on detection sensitivity and reaction in near-wall of microchannel. As effect of van der Waals force and electrostatic force is large, lift force acted to particle is neglected. In this paper, effect of flow on concentration of particle in micro-channel was measured. Evanescent wave was used for observation of particle. Change in the lift force acted to particle was measured and the effect of the lift force on the concentration of the particle in near-wall. The results show that as the velocity gradient increases, the peak position of concentration of particle has parted from near-wall.
