Adequate characterization of NPs (nanoparticles) is of paramount importance to develop well defined nanoformulations of therapeutic relevance. Determination of particle size and surface charge of NPs are indis- pensable for proper characterization of NPs. DLS (dynamic light scattering) and ZP (zeta potential) measure-.

zeta potential is a very good index of the magnitude of the interaction between colloidal particles and measurements of zeta potential are commonly used to assess the stability of colloidal systems. Origins of Surface Charge. Most colloidal dispersions in aqueous media carry an electric charge. There are many origins of this
The zeta potential (ZP) is a function of the surface charge which develops when any material is placed in a liquid. It is a This offers the possibility of measuring the complete mobility spectrum. Over the past are illustrated using examples from measurements of various oxides and non-oxides commonly used in ceramics

The electrostatic potential on that surface is called the zeta potential and it is that potential which is measured, when one measures the velocity of the particles in a d.c. electric field. The velocity (in metre/second) for a unit field strength (1 Volt per metre) is called the electrophoretic mobility, and is given the symbol µE.
Besides, the zeta-potential characterizes the electrical double layer on the solidmiquid interface, a fact very important in flotation and flocculation processes ( 0 c e p e k, 1989). In this paper the zeta-potential measuring methods. (electrophoresis, electroosmosis, streaming potential and sedimentation) are described as well

The aim of this chapter is to describe the basic Zeta potential measurement principles behind the Zetasizer Nano. This will help in understanding the meaning of the results achieved. The chapter is divided into two major sections. What is Zeta Potential? and. Operation of the Zetasizer Nano - Zeta potential measurements.
