Nanosize particle analysis by dynamic light scattering (DLS)

Abstract

Dynamic light scattering (DLS) is used for measuring average particle diameter and particle diameter distribution of nano-sized particles dispersed in liquid. The parameters are important characteristics mainly for drug delivery system (DDS) formulations, such as solid in oil (S/O) formulations, liposome formulations, suspension formulations, and emulsion formulations. Herein are described a measurement method and measurement case of particle diameter analysis of medical products using laser light.
