Small-angle X-ray scattering – analyzing size and structure of nanoparticulate systems
Small-angle X-ray scattering (SAXS) is an analytical method used to determine the structure of nano-sized particle systems in terms of averaged particle sizes or shapes. In a SAXS experiment the scattering signal differs for particles of different sizes and therefore provides results regarding their size and size distribution. Furthermore, when all particles have the same size the scattering pattern is characteristic of their shape, i.e. SAXS can differentiate between spherical, cylindrical, and prolate/flat particles.
The possibility to evaluate the size and shape of various particles makes SAXS an important analysis tool in the field of materials, both in academic research and industrial applications. The determination of the nanoscopic structure of particulate systems provides valuable information on their macroscopic properties. Typical materials of interest are quantum dots, catalyst systems, surfactants, colloidal solutions, and many more.
