Debye Screening – what is it?   In colloidal samples (and this spans the whole range from molecules in solution to particles in a dispersion) the movement of and forces between objects are often governed by the charge affecting neighbors….READ MORE >

How good can a gold standard be?   When performing dynamic light scattering (DLS) measurements, we sometimes encounter especially nice data. An interesting issue to consider is the level of data quality one can expect to achieve. What is the…READ MORE >

Where is the Zetasizer used?   For around two decades, the Zetasizer range has been the de facto standard for performing dynamic light scattering (DLS) measurements on a wide range of particles and materials. Today’s launch of the Zetasizer Pro and…READ MORE >

Do refractive index and absorption matter for nanoparticles? Abstract: Refractive Index of Gold, Silver, Titanium and Other NanoParticles FAQ: How important are refractive index and absorption for nanoparticles? In general, the optical properties of the scattering material have a tremendous…READ MORE >
