Small-Angle Scattering Research Group

Overview of Research Group, Goals and Purposes:

　Small-Angle Scattering Research Group consists of the members who analyze the structures of the bio and soft matters with small-angle X-ray scattering and the members exchange various information on the bio and soft matters. We have obtained gyration radius and correlation length with Guinier and Ornstein-Zernike approximations, respectively, and also have structure parameters by fitting with model functions from SAXS. Recently, according to development of a computer simulation technique, we have being derived three-dimensional structure of protein and its dynamical aspect from SAS data by MC-SAXS and MD-SAXS techniques. In this group, we improve these analysis techniques and also are challenging to understand variety of bio and soft matter mechanism with the improved techniques.
As a next step, our group focuses on the dynamical properties of bio and soft matters. We believe that X-ray photon correlation measurement is one of promising techniques to explore the dynamics of the bio and soft matters. In particular, X-ray photon correlation measurement with high coherence X-ray would explore not only the dynamics of protein but the cooperative dynamics of the hierarchical structures of the bio and soft matters. By revealing these dynamics, it is considered that our goal is understanding of biological phenomena in the frame incorporating expression of function by self-organization.
