Light scattering can be measured using several techniques, including Dynamic Light Scattering (DLS), Static Light Scattering (SLS), and Small-Angle X-ray Scattering (SAXS). DLS is commonly used to determine the size distribution of nanoparticles in a colloid by analyzing the fluctuations in light intensity over time. SLS measures the total intensity of scattered light to provide information about molecular weight and size. SAXS is used for structural analysis of nanoparticles in various states.
