Dynamic Light Scattering (DLS)

Dynamic Light Scattering (DLS) is a highly sensitive analytical technique designed to measure the size and distribution of particles and molecules in solution with remarkable precision. Unlike general particle sizing methods, DLS delivers fast, repeatable, and nanometer-scale resolution, making it the preferred tool for characterizing nanoparticles, proteins, polymers, and colloids in both research and industrial settings.

Dynamic Light Scattering determines particle size by measuring fluctuations in laser light scattered by particles undergoing Brownian motion in suspension. The diffusion rate is used to calculate the hydrodynamic diameter, providing rapid, non-destructive analysis of size distribution with high sensitivity ideal for quality control and formulation in industrial processes.

DLS can effectively analyze and characterize a wide range of materials, including:

• Nanoparticles and liposomes

• Proteins, peptides, and enzymes

• Biologics and biosimilars

• Polymers and dendrimers

• Emulsions, suspensions, and colloids

• Virus particles and extracellular vesicles

• Drug delivery systems

• Environmental and industrial nanomaterials
