Dynamic light scattering (DLS), sometimes referred to as Quasi-Elastic Light Scattering (QELS), is a non-invasive, well-established technique for measuring the size and size distribution of molecules and particles typically in the submicron region, and with the latest technology lower than 1nm.
Typical applications of dynamic light scattering are the characterization of particles, emulsions or molecules, which have been dispersed or dissolved in a liquid. The Brownian motion of particles or molecules in suspension causes laser light to be scattered at different intensities. Analysis of these intensity fluctuations yields the velocity of the Brownian motion and hence the particle size using the Stokes-Einstein relationship.
Dynamic light scattering technology from Malvern Instruments offers the following advantages:

Nanoparticles are defined by their size. In this presentation different sizing techniques are compared, with a focus on experimental tips and tricks to get maximum value from sizing techniques such as dymamic light scattering with the Malvern Zetasiz...
Ultra-Fine (nano) bubbles have garnered increasing interest over the last few years as they open up the potential for improvements in a variety of applications from cleaning to agriculture. However they are still somewhat a mystery with respect to th...
Polymeric materials are the most studied of all rheological materials and polymeric solutions in particular are perhaps the most interesting. They are ubiquitous in every-day life and play an important role in applications ranging from joint lubricat...
This article explores the benefits of fully automated, high throughput particle size and formulation stability measurements and presents data to show how a new autosampler for the widely used Zetasizer Nano particle characterisation syste...
The second virial coefficient (A2, B22) has been identified as a potential parameter to assess and optimize formulation stability. Traditionally, the measurement is time consuming in batch mode, since preparation of various concentrations...
