Overview

 

Accurately measuring the stability of biological molecules is a critically important step in the development of novel biologic-based therapeutics. Since nanoparticle properties such as size and zeta potential may influence particle uptake by target cells and/or tissues in vivo, light scattering technologies represent an important tool to investigate the physicochemical properties of miRNA-delivery systems. Here we demonstrate that the Litesizer™ 500 returns rapid and precise results despite very low sample concentration and volume. We used dynamic light scattering (DLS) for particle size measurement and a novel, patented electrophoretic light scattering technology called cmPALS for zeta potential determination.

Continuously Monitored Phase Analysis Light Scattering (cmPALS) enables faster and more reproducible zeta potential analysis. Specifically, the technology includes an additional monitor that measures and removes any non-linearities in the frequency modulator and thus enables faster measurements at lower voltages with improved reproducibility.
