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:

The ability to measure accurate particle size across a range of concentrations and sizes whilst maintaining consistent results is critically important in ensuring you can trust your data and develop an understanding of your application. This paper he...
This webinar introduces the Nanoparticle Tracking Analysis (NTA) technique and how it affords useful information in various synthetic nanoparticle systems. We will discuss how NTA was used to measure the effects of certain buffers on the aggregation...
The basis of agglomeration and aggregation is the attraction that particles and particle groups have for one another. We'll outline the various forms of atttaction (van de Waals, capillary etc ) and thus show how a gecko can walk on the ceiling.
In the early history of cryptography and ciphers then invisible inks using silver salts and other chemicals were used. Silver colloids were regularly used and abused in this area. Silver colloids are now finding application (and legislation) as bater...
A detailed understanding of the mechanism of unfolding, aggregation, and associated rheological changes is developed in this study for β-Lactoglobulin at different pH values through concomitant measurements utilizing dynamic light scattering (DLS), o...
