Two methods were applied to characterize the dimensions of nanoparticles in colloidal solution. Dynamic light scattering and acoustic attenuation spectroscopy are compared with one another. The accuracy and precision of these two methods applied to nanoparticles of silica were determined. The advantages and disadvantages of the methods of dynamic light scattering and acoustic spectroscopy in determining the size of nanoparticles are revealed.

MEASUREMENT OF SILICA NANOPARTICLE SIZES BY THE DYNAMIC LIGHT SCATTERING AND ACOUSTIC ATTENUATION SPECTROSCOPY METHODS
Nanoparticles have properties that depend critically on their dimensions. There are large numbers of methods that are commonly used to characterize these dimensions, but there is no clear consensus on which method is most appropriate for different types of nanoparticles. In this work, two different characterization methods were applied to characterize the dimensions of nanoparticles in colloidal solution. Namely, dynamic light scattering and acoustic attenuation spectroscopy are compared with one another. The accuracy and precision of these two methods applied to nanoparticles of silica were determined. In addition, the advantages and disadvantages of the methods of dynamic light scattering and acoustic spectroscopy in determining the size of nanoparticles are revealed.
