This information can then be used to derive the hydrodynamic size of objects in suspension. DLS measures the stochastic temporal variations in the scattered laser light, resulting in a time autocorrelation function describing the timescales of mutual diffusive motion of the scattering objects. Scattering Methods Applied to Soft Condensed Matter ( Elsevier Science B.V., 2002). Pusey, “ Introduction to scattering experiments,” in Neutrons, X-Rays and Light. Light scattering has long been used for the characterization of soft matter and dynamic light scattering (DLS) has demonstrated itself to be a crucial and indispensable technique to investigate the dynamics. Correlating the microscopic behavior with these macroscopic processes is thus a fertile ground for research. (00)00141-1 Soft materials also offer the possibility to investigate many of the key topics in soft condensed matter in general, such as slow reactions and kinetics, aging processes, gelation, controlled release, food processing, micellar growth, and aggregation phenomena.
