SANS (Small Angle Neutron Scattering)

Small Angle Neutron Scattering (SANS) is a technique that uses neutrons—uncharged particles—to study the structure of materials at a microscopic scale, typically from 1 to 100 nanometers. By directing a beam of neutrons at a sample and analyzing how they scatter at small angles, scientists can infer details about the size, shape, and arrangement of tiny features like polymers, proteins, or pores. This method is non-destructive and highly sensitive to differences in material composition, making it valuable for understanding complex biological and synthetic systems at a molecular level.
