What is the significance of hydrodynamic size of particles which is measured by Dynamic Light Scattering (DLS) ?

04 April 2016 1 7K Report

I have read in an article that "Maximum hydrodynamic size of the Cr2O3 particles was observed as 120 nm and 350 nm for MnCr2O4." what's the significance of this consequence? I mean to say that what kind of sense these results are made?

Yuri Mirgorod

Dear Adhan:

The hydrodynamic size measured by DLS is defined as the size of a hypothetical hard sphere that diffuses in the same fashion as that of the particle being measured. Most of the obtained nanoparticle size distribution. Your friends are distributed on growth. There is small growth and large growth. If your semipermeable membrane will have a maximum pore size of 100 nm, it will delay all particles Cr2O3.

Best regards.

The hydrodynamic size of nano-particles is mostly greater than 100 nm, then how can we say that these are nano-particles? Is there any justification?
