| Outline of Final Research Achievements |
Recently, a new fluid engineering field exploiting 10-100 nm space smaller than the light wavelength is in the initial stage. A spatially- and temporally resolved measurement method for this ultra small space is required to understand fluid flows where surface effects appear. The objective of this research project is to establish a measurement method for flow velocity distribution in nanochannels utilizing nanoparticles and evanescent wave light near the wall within 100 nm, considering dominant surface effect in nanospaces. A measurement system to accurately detect flowing nanoparticles was developed. By using this system, we could reveal unique behavior of nanoparticles in nanospaces such as nonuniform distribution of nanoparticles and anisotropically hindered nanoparticle diffusion. The knowledge obtained from this project is important for establishment of the measurement method.
