| Research Abstract |
The purpose of this research project is to establish a novel technology to transport small particles using an optical radiation pressure and a locally controlled property variation. A microdevice controlling particles by the optical force and a measurement system were developed. It is confirmed that the ability to manipulate particles by the optical pressure is enhanced by 60% using locally reduced viscosity due to absorption of the light energy irradiated into the liquid. Additionally, applying alternating-current electric fields to an electrode array results in a particle transportation caused by the temperature dependent electrical conductivity.
