Zeta Potential: A Fundamental Measure for Colloidal Behavior
What is Zeta Potential? Figure 1. Electrical double layer at the surface of solution-phase nanoparticles. Zeta potential (ZP) is a physical property exhibited by any particle in a suspension, macromolecule or material surface. ZP is an analytical technique used to determine the surface charge of nanoparticles in colloidal solutions. The surface of a charged particle attracts and binds firmly...
