Characterization of magnetic nanoparticle by dynamic light scattering
Here we provide a complete review on the use of dynamic light scattering (DLS) to study the size distribution and colloidal stability of magnetic nanoparticles (MNPs). The mathematical analysis involved in obtaining size information from the correlation function and the calculation of Z -average are introduced.
Dynamic light scattering (DLS) is the most accepted and used technique for submicron particle size analysis. Since DLS is a “first principles” technique, systems are not calibrated but accuracy performance should be verified during installation and annually thereafter.
Dynamic light scattering: a practical guide and applications in ...
Dynamic light scattering (DLS), also known as photon correlation spectroscopy (PCS), is a very powerful tool for studying the diffusion behaviour of macromolecules in solution. The diffusion coefficient, and hence the hydrodynamic radii calculated from it, depends on the size and shape of macromolecules.
Understanding Dynamic Light Scattering - Wyatt Technology
In dynamic light scattering (DLS), the time-dependent fluctuations in the scattered light are measured by a single photon counting module. The rate of fluctuations is directly related to the rate of diffusion of the molecule through the solvent, which is related in turn to the particles' hydrodynamic radii.
