Dynamic Light Scattering (DLS) is an analytical technique used to determine the size distribution of particles in a liquid or colloidal suspension by analyzing the fluctuations in scattered light intensity over time. These fluctuations arise from the Brownian motion of particles, and their speed depends on particle size: smaller particles move faster, causing quicker intensity changes. DLS provides rapid, non-invasive, and highly sensitive measurements, making it particularly useful for characterizing nanoparticles, proteins, and polymers.
Its key benefits include high resolution for detecting small size differences and the ability to measure samples at low concentrations without extensive preparation. DLS finds widespread applications across industries, including pharmaceuticals for drug formulation and stability studies, biotechnology for protein aggregation analysis, materials science for nanomaterial characterization, and cosmetics for understanding emulsion properties.
