Aug 10, 2016 · Determination of particle size and surface charge of NPs are indispensable for proper characterization of NPs. DLS (dynamic light scattering) and ZP (zeta potential) measurements have gained popularity as simple, easy and reproducible tools to ascertain particle size and surface charge.

Dynamic light scattering provides insight into the dynamic properties of soft materials by measuring single scattering events, meaning that each detected photon has been scattered by the sample exactly once. In principle, the DLS measurements can be performed with the detector positioned at any angle.

Oct 20, 2024 · Dynamic light scattering (DLS) is a useful tool for the study of the solution-based behavior of colloids and molecular assemblies. The aim of this methods paper is to provide perspective on how this technique can be used by supramolecular chemists.

Our dynamic light scattering (DLS) products operate in traditional cuvette as well as on-line and automated, high-throughput modes. We also offer unique instruments for electrophoretic light scattering (ELS), differential refractometry and differential viscosity.

The Entegris Nicomp® dynamic light scattering (DLS) system is an easy to use particle size and zeta potential analyzer. This technical note shows typical results from the Nicomp and explains how to interpret the data generated.

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, …

Let us discuss the theory of DLS, which will tell us how the measured intensity autocorrelation is related to diffusion constant as well as particle size distributions.

Is DLS used to measure zeta potential or does it measure the hydrodynamic diameter of nanoparticles? What is the mechanism behind measuring zeta potential and does it differ from DLS?

The ZetaStar measures back-scatter dynamic light scattering simultaneously with ELS for size, polydispersity and zeta potential, or side-scatter DLS together with 90° SLS to determine size, polydispersity and particle concentration (or molar mass for macromolecules).

Automatically screen dozens or hundreds of nanoparticle formulations for size by DLS with a DynaPro Plate Reader. Simultaneous static and dynamic light scattering measurements in a DynaPro NanoStar cuvette-based DLS instrument reveal …
