Dynamic light scattering experiments
WebJan 1, 2024 · Dynamic light scattering (DLS) is an optical measurement technique for the characterization of disperse systems. The technique evaluates high-frequency fluctuations in scattered light, which reflect the dynamics of microstructural processes, such as elastic vibrations in gels, sol–gel transformation, or particle agglomeration. WebFeb 16, 2024 · Dynamic light scattering (DLS) is a fast and non-invasive tool used to measure particle size, size distribution and stability in solutions or suspensions during nanomaterial preparation.
