Zeta Potential: A Sensitive and Versatile Parameter for the Characterization and Design of Advanced Materials

The properties of material-water interfaces determine the stability of nanoparticle dispersions or protein adsorption on a biomaterial’s surface. Among these properties, surface charge drives electrostatic interaction. Both charge and electrostatic forces are best assessed by analysis of the zeta potential.

In this webinar, guest speaker Dr. Sara Ferraris of Politecnico di Torino will offer insights into her research activities and share her experience with zeta potential analysis for advanced materials characterization.

You will learn about the complementary analytical techniques of electrophoretic light scattering and streaming potential for zeta potential analysis in colloidal dispersions and at solid-water interfaces.

We will focus on the characterization of titanium for dental implants and artificial joints as a selected biomaterial, and the effect of tanning agents on leather.
