Abstract

Understanding fluid flows in extended nanospace (10-1000 nm) is important for novel nanofluidic devices. Considering the fluid slip and unique liquid properties with heterogeneous liquid structure reported previously, extended- nanoscale fluid dynamics with molecular picture is required. Here, we developed an evanescent wave-based particle tracking velocimetry for extended nanochannel flows. The velocity distribution of pressure-driven flows in a 410 nm fused-silica channel was successfully measured. The results indicated slip velocities even in hydrophilic channel. We suggest a possibility for appearance of moelculear behavior in the fluid near the wall within 100-molecular thickness, which is close to the limit of continuum regime.
