| Outline of Final Research Achievements |
In order to create an ultimate chemical reaction system exploiting 10 nm nanospaces to make single-molecules collide and react, here we developed fundamental technologies and obtained fundamental knowledge of the mass transport. Fabrication of a square-shaped nanochannel of 50 nm size in minimum and 3 nm roughness was achieved by developing a top-down fabrication process. A technology for controlling the density of silanol group on the channel surface exploiting dehydration reaction was also developed. In addition, we revealed that the electrostatic interactions by the nanochannel surface significantly affect behavior of solute molecules. Accordingly, we established technologies of nanochannel fabrication and surface control for the single-molecule collision/reaction system and obtained a guideline of the surface control for the mass transport.
