Outline of Final Research Achievements

Nanopore devices consisting of a surround gating electrode causing a decrease in speed of nanomaterials passing through the nanopore have been fabricated in order to analyze structures of the materials. The gating voltage via a gating electrode resulted in 240 times slower speed of nanoparticles passing through a nanopore than that without the gating voltage, and DNA also showed 10 times slower speed under the gating voltage. In addition, the shapes and structures of these materials passing through a nanopore were quantitatively revealed by analysing changes in ionic current due to the material translation.
