Outline of Final Research Achievements

The fast-scanning atomic force microscope (FS-AFM) for single-molecule imaging to measure the phenomenon that matter was transported along a polymer chain was produced. The method to measure the micro-Brownian motion was developed. The phenomenon that matter (short chain) was transported along one helical chain (long chain) of poly(substituted phenylacetylene) by single-molecule imaging using FS-AFM was observed, and diffusion coefficient were measured.
In addition, the following results were also provided. (1)A temperature control imaging experiment, (2)The molecular dynamics simulation of the matter transportation phenomenon, (3)The understanding of the matter transportation phenomenon by the visualization analysis (PIV) of a solvent flow generated at a long-polymer-chain neighborhood, (4)Control of the matter transportation.
A molecular walk (a molecular motor principle) in an organic solvent was demonstrated. I want to create the non-aqueous solution-based artificial life function.
