understanding the state of the nanoparticle surface and predicting the long term stability of the nanoparticle. At nanoComposix we routinely use Zeta Potential analysis to determine if a surface modification to the nanoparticle has been successful or if a processing step has modified the nanoparticle ...
force balance exerted on particles in a nanopore and a current sensing technology to measure the zeta potential of the nanopore accurately, and then uses the measured zeta potential of the pore to further measure the zeta potential of the electrically charged nanoparticle passing through the pore. ...
Therefore, the measurement of the ζ-potential via electrophoretic light scattering (ELS) has become essential for nanoparticle (NP) research. However, the interpretation of NP electrophoretic mobility, especially that of ligand-coated NPs, can be a complex undertaking. Despite the inherent intricacy ...
Nanoparticle and colloidal suspension stability often depends on the surface charge of the particles. In some applications, stability is desired and the effect of suspension conditions such as pH on electrostatic stabilization should be evaluated or moni

5.2.3 Zeta potential Zeta potential is a measure of surface charge that is regarded as a valuable parameter by both the scientific community and regulatory agencies. It is a measure of the difference between a nanoparticle's electrostatic potential and that of the bulk solution. To obtain the ...
The main goal of this ILC was to identify competent collaborators for the production of certified nanoparticle reference materials. 38 laboratories from four different continents participated in the ILC with different methods for particle sizing and determination of zeta potential. Most of the ...
Characterization of particles is on the center stage in nanotechnology development. The subjects for nanoparticle characterization are currently focused on particle size and particle surface charge. The particle surface charge, characterized by zeta potential, is vital in R&D and QC...
The BeNano Series is the latest generation of nanoparticle size and zeta potential analyzers designed by Bettersize Instruments. Dynamic light scattering (DLS), electrophoretic light scattering (ELS), and static light scattering (SLS) are integrated into the system to provide accurate measurements of pa...
In order to find out the effect of pH on the particle size and zeta potential, HA/CS-plasmid nanoparticles prepared with CS:HA weight ratios of 4:1, for example, were prepared by changing the pH value of the nanoparticle solution from 5.5 to 8.0 shortly after preparation. The particle ...
