WebbSmall-angle X-ray scattering (SAXS) is a powerful method to study the structural properties of materials at the nanoscale. Recent progress in instrumentation and analysis methods has led to rapidly growing applications of this technique for the characterization of biological macromolecules in solution. WebbSmall-angle X-ray scattering (SAXS) is a small-angle scattering technique which is sensitive to nanoscale differences in the electron density of a sample. When X-rays travel through the material, their elastic scattering at small angles is recorded. This allows to determine the size, shape, and oligomeric state of biological macromolecules on a ...
