Question

Why the hydrodynamic size of the nanoparticles are different from the tem calculated size

Answer 1

In contrast to TEM which is a direct measurement of physical particle size (and shows AuNPs to have an average diameterof 100 nm), PSD and DLS estimate particle hydrodynamic radius. ... Given that DLS is an intensity-based measurement system, this can cause errors in the particle sizemeasurement.
