Novel Predictive Model for Zeta Potential of Metal Oxide Nanoparticles

What is it about?

In this paper the relationship between zeta potential and physico-chemical features of metal oxide nanoparticles is developed. The developed here Quantitative Structure-Property Relationship model (nano-QSPR) was capable to predict ζ of metal oxide nanoparticles utilizing only two properties: (i) the spherical size of nanoparticles – a parameter from numerical analysis of Transmission Electron Microscopy (TEM) images and (ii) the energy of the highest occupied molecular orbital per metal atom - a theoretical descriptor calculated by quantum mechanics at semi-empirical level of theory (PM6 method).

Why is it important?

This is the first study that was able to model and predict zeta potential for metal oxide nanoparticles in solution.
