| Research Abstract |
In 2000, we successfully conducted in vitro time-resolved X-ray observations of picometer-scale slow Brownian motions of individual protein molecules in aqueous solutions. In this single-molecule detection system, which we call diffracted X-ray tracking (DXT), we observed the rotating motions of an individual nanocrystal labeled to a specific site in individual protein molecules by using the time-resolved Laue diffraction technique. It is the purpose of this research that we perform the compact DXT instrumentation which enables measurement of the single molecule of this high precision pursuing method on a laboratory level. There were three technical points for realization. We succeeded in the new nanocrystal’s production, x-ray condensing, and a background’s reduction.
