N2 - Understanding ion transport phenomena in extended nanospace (10-1,000 nm) is important for the evolution of nanofluidic devices. We developed non-probe measurement system of electric conductivity of water for elucidating proton transport in the extended nanospaces. The results showed that conductivity in extended nanospace was approximately 500 times higher than that in bulk. The measured conductivity was consistent with the calculated one, which was determined using electric double layer (EDL) model and specific macroscopic parameters previously measured in extended nanospaces. It will be important information for nanofluidics.
