Express method for particle size analysis in solid, liquid, and amorphous materials using 3D calibration curve and 2D-DLS dynamic light scattering

Abstract

This study proposes a new method for particle size studying based on the use of topological descriptors for various media and types of matter. The sizes of supramolecular particles in water-lactose complexes were studied using the diffuse dynamic light scattering (DLS) method. Mist-Standart latex balls were used to generate a 3D calibration curve, followed by empirical particle size determination. In order to confirm the output, the resulting sizes were compared for a number of silver proteinate solutions, preliminary analyzed by laser light scattering (using ZetaSizer equipment by Malvern Instruments Ltd, UK). The new method uses a simplified procedure, provides a quick solution and may be used for both quality control of cloudy and opaque medicinal substances and excipients as well as in other fields of nanotechnology. Keywords: nanoparticles, particle size, silver proteinate, latex nanoparticles, dynamic light scatterin
