Outline of Final Research Achievements

To elucidate transport phenomena for fluid in a nano-space, nanogap-embedded nanopore devices were fabricated and a measurement system by impedance spectroscopy was developed. Parasitic capacitance of the nanogap electrodes was reduced lower than the order of fF by fabricating the device on a glass substrate, and the measurement system, which enables us to measure devices of GΩ and higher impedance, was developed. By using these system, diffusion phenomena in nanogap-nanpore devices was observed.
