Abstract

Understanding liquid properties in extended nanospace (10-1000 nm) is important for nanofluidic devices. Our group found unique liquid properties in fused-silica extended nanochannels and surface silanol groups have been considered to play a key role in these properties. Here, we controlled surface silanol density in extended nanochannels and evaluated proton transfer in water molecules confined in the channels. The result of NMR measurements strongly suggests that surface silanol groups enhance proton transfer in extended nanospace. Our result contributes to development of nanofluidic devices.
