| Outline of Final Research Achievements |
Microfluidics has rapidly developed to miniaturize and integrate various fluidic operations. Recently, it has been further downscaled to nanofluidics. In this study, in order to understand fluid flows in ultrasmall nanospaces, we proposed a measurement method of flow velocity distribution by tracing the motion of single-molecules in fluid flows, which we call molecular image velocimetry (MIV). A tracer molecule with controlled size was developed by fluorescence modification of dendrimer, and applied to measurements of pressure-driven flow in a nanochannel. The proposed method and obtained knowledge will contribute to understand fluid dynamics and molecular transport in nanospaces.
