Nanoparticles with a zeta potential between -10 and 10 mV are considered approximately neutral, while nanoparticles with zeta potentials of greater than 30 mV or less than -30 mV are considered strongly cationic and strongly anionic, respectively. Since most cellular membranes are negatively charged, zeta potential can affect a nanoparticle’s tendency to permeate membranes, with cationic
Zeta sizer and transmission electron microscopy (TEM) were used to characterize and determine the size and size distribution of the synthesized gold nanoparticles. Results: In the present work optimal gold salt concentration, trisodium citrate concentration and temperature were found to be
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 of these data, key concepts from colloidal science can help to distill valuable information
Zeta potential was also measured using a Zetasizer Nano ZS (Malvern, UK) for recognition. Before and after the modification, each sample was examined by CuK α …
Positively charged nanoparticles or nanoparticles with higher ‘like’ charges, offered higher interaction force with cells. Conclusion This work proposes a novel approach for investigating interaction between NPs and cells, and discloses the importance of controlling zeta potential in developing NPs-based formulations in the future.
Depending on the configuration and application the system can be used as a particle size analyzer, or also used to measure zeta potential, molecular weight, (MW) and second virial coefficient (A2). Typical applications for the SZ-100 include nanoparticles, colloids, emulsions, and submicron suspensions.
The effect of nanoparticle concentration on zeta-potential measurement results at dilute concentrations was evaluated. The values of the zeta-potential for four different types of nanoparticles, Ludox (silica), multi-walled carbon nanotubes (bamboo-shaped and hollow nanotubes) and gold, at various concentrations, were obtained using a laser
Antibiotics 2018, 7, 51 3 of 14 the mean values of 89 21 and 19 4 nm for the green and conventional formulation, respectively. The values of zeta potential of green and conventional silver nanoparticles were lower than 30 mV
