Abstract
Frequently, the size, size distribution, and shape of particles are crucial to their function. Hence, determining particle morphology is significant, and many methods have been developed for this purpose. Dynamic light scattering (DLS) is a noninvasive technique that has been widely used in chemistry, physics, polymer science, colloid chemistry, material science, biophysics, biochemistry, industrial biophysics, etc., for measuring the size, size distribution profile, and shape of particles in suspension or polymers in solution. It generally allows one to measure submicrometer particles and can also be used to determine particles with sizes less than a nanometer. DLS is also performed to investigate the slow dynamics, verification processes, and gelation processes of particles. This chapter discusses the use of DLS as an efficient and nondestructive characterization technique of particles.
