ze·ta po·ten·tial

the degree of negative charge on the surface of a red blood cell; that is, the potential difference between the negative charges on the red cell and the cation in the fluid portion of the blood.

The surface functionalization of the particles was then investigated by zeta potential measurements.
As shown in Figure 8(a), the addition of APA as a dispersant agent and the zeta potential of the powder surface do not change much from the initial pH value, except the strong acidic range and higher zeta potential cannot be accepted in a more basic condition.
gave attention and conducted preliminary studies on inducing particle-wall effect in electroosmotic flow; Peng then experimentally found that the higher the zeta potential of the electrical double layer around the surface of the polarizable solid, the more particles agglomerated; demonstrating the feasibility of using micronanoparticle manipulation to induce electroosmosis.

Zeta Potential. The zeta potential was determined by Dynamic Light Scattering (DLS) measurements on a Zeta-Sizer Malvern at 25[degrees]C in an aqueous medium after dispersion for 30 min in an ultrasound bath.
Vesicle Size, Size Distribution, and Zeta Potential. The vesicle size, size distribution, and zeta potential of PR-containing ethosomes were determined using a Zeta Potential Analyzer (Model ZetaPALS, New York, USA) at 25[degrees]C with a scattering angle (0) of 90 degrees after diluting 10 [micro]l of the vesicular formulation with 4 ml of Milli-Q water.
