DLS (Dynamic Light Scattering)

Dynamic Light Scattering (DLS) is a technique used to measure the size of tiny particles or molecules suspended in a liquid. When a laser light hits these particles, they scatter the light in different directions. By analyzing how the scattered light fluctuates over time, DLS can determine how fast the particles are moving due to their Brownian motion. This information is then used to calculate the average size of the particles. DLS is commonly used in research and industry to characterize nanoparticles, proteins, and other small particles in solutions.
