small angle neutron scattering

Small Angle Neutron Scattering (SANS) is a scientific technique used to study the structure of materials at the nanometer scale. By directing neutrons—uncharged particles—from a neutron source onto a sample, researchers can observe how these neutrons scatter at small angles. This scattering provides information about the size, shape, and arrangement of particles within the material. SANS is particularly useful for investigating complex substances like polymers, biological samples, and soft matter since it can reveal details about their internal structures without destroying them.
