explain the zeta potential in briefly.?
Answers
Answer:
The zeta potential (ζ-potential) is the potential difference across phase boundaries between solids and liquids. It's a measure of the electrical charge of particles are that are suspended in liquid. ... In colloids, zeta potential is the electric potential difference across the ionic layer around a charged colloid ion.
Answer:
Zeta potential (ZP) depends on the composition of SLNs and is a function of the particle's environment. Electrophoretic light scattering (ELS) and electroacoustic determination are the techniques used for ZP analysis. ELS provides better resolution and more reliable results than other methods. Aggregation of SLNs can be created by small size, large surface area, and free energy of nanoparticlesThis parameter shows the degree of repulsion between the charged particles in the dispersion. High ZP implies highly charged particles, which prevents aggregation of the particles due to electric repulsion. If the ZP is low, attraction overcomes repulsion, and it is likely that the mixture forms coagulates [45]. The ZP value of −30 mV is considered optimum for good stabilization of a nanodispersion
