Nanoparticle characterisation using the Zetasizer Nano from Malvern Instruments is providing essential information for researchers working on drug delivery systems at UK's newest school of pharmacy
Particles several nanometers in diameter are used to impart the required properties while maintaining the transparent nature of the finished film.
Photon correlation spectroscopy, the particle sizing technique used by the Zetasizer Nano is ideal for the analysis of products such as these, offering rapid measurement with minimal sample preparation.
While important visual aspects of paint performance, such as hue, gloss and opacity, correlate directly with particle size, zeta potential is a critical variable when investigating product stability.
Paints are complex multicomponent suspensions, the performance of which is detrimentally affected by agglomeration and/or sedimentation during storage.
The measurement of the zeta potential of each of the constituents as a function of variables such as pH and dispersant composition, facilitates manipulation of the formulation composition to deliver products with the required stability. Request a free brochure from Malvern Instruments ...
