Dynamic Light Scattering (DLS) measures the translational diffusion coefficients Dt of nanoparticles and colloids in solution by quantifying dynamic fluctuations in scattered light. Sizes and size distributions, in turn, are calculated from the diffusion coefficients in terms of hydrodynamic radius rh or hydrodynamic diameter dh. DLS is suitable for ensemble measurements ranging from rh values of 0.2 nm up to 5,000 nm. Wyatt offers high-throughput, automated DLS as well as conventional, cuvette-based formats.

Dynamic Light Scattering Products

DynaPro® NanoStar®

The DynaPro® NanoStar® is a unique cuvette-based DLS instrument used for the analysis of proteins, promiscuous inhibitors, micelles, quantum dots, liposomes, metallic nanoparticles and more. To accommodate scarce and precious samples, specially designed quartz cuvettes afford robust, accurate measurements with as little as 1 ┬ÁL of solution, while our proprietary disposable cuvettes provide comparable sensitivity with as little as 4 µL!

DynaPro Plate Reader III

The DynaPro Plate Reader III offers dynamic light scattering (DLS) and static light scattering (SLS) measurements of the size, molecular weight and interactions of proteins, nanoparticles and other macromolecules in situ in industry-standard microwell plates. No liquid handling occurs after dispensing into the plates, to maximize throughput and minimize sample carryover.
