| Outline of Final Research Achievements |
Temperature gradient in continuous fluids induces the motion of dispersed micro/nano particles even when fluids are motionless. This phenomenon is known as thermophoresis and is expected to develop a novel control technique of the particle motion. However, the driving mechanism of thermophoresis is not yet fully understood. In this research, we carried out some experimental studies to investigate thermoelectric effect in water solution. Thermoelectric effect is expected to play a key role in thermophoresis. In fact, we found that the addition of NaOH to water solution reverses the direction of thermophoresis of micro particles. Moreover, we developed an on-chip microfluidic device which utilizes thermophoresis for the controｌ of microparticle motion.
