Structural Biology

Small-Angle X-ray Scattering is a powerful technique to study the structure and interactions of various systems with a typical size on the order of 1 nm to 100 nm. Particularly the properties of biological macromolecules such as DNA and proteins can be determined by SAXS.

The newly installed SAXS/WAXS system can be used for the following researches:

  1. Structure of materials (crystalline, amorphous, or porous)
  2. Solution structure of nanoparticles, colloids, surfactant, polymer or biomacromolecules (protein or DNA)
  3. Kinetics of phase transition, self-assembly, etc.
