PIVによるマイクロチャネル内電気浸透流の可視化計測
The micro PIV system has been developed as a new diagnostic tool for microscale flow and applied to the measurement of microchannel flow in order to investigate the properties of electroosmotic flow. The field of view of the PIV system is 580 μm×580μm and velocity vector fields can be measured at 9.3μm vector-to-vector intervals using two-frame cross-correlation method with 32×32 pixels interrogation spot. In this study, two different types of microchips, which are developed for genetic analyses, are employed : PDMS (polymethylmethacrylate) microchip and PMMA (polydimethylsiloxane) microchip.
