Abstract
Simple and easy evanescent wave generating device "Evanescent Wave for a Chip" (EvaChip) was developed. The purpose of this study is to measure pH distribution and velocimetry vector map of flow in the vicinity of liquid-solid interface by using 3CCD camera. Nano-PIV and nano-LIF were carried out by using particles and dye with different emission wavelength, respectively. EvaChip was improved to measure with high SN ratio so as to measure in both methods. Based on the results, in order to investigate the effect of thermofluid phenomena to the chemical reaction, simultaneous measurement will be carried out by using EvaChip.
