It means that on the surface your nanoparticles has a net positive charge and so you your nanoparticles have superficial groups with positive charge. And when your nanoparticle has a great absolut value (30mv) the zeta potentil indicate that your particle form stable suspention on water.

Hi, dear Minitha C R,

It is so nice could to help you with your questions.

I am attaching you a first document you should read in order to get the initial knowing about these thems.

Greetings from Prof.Dr.OLSM

The Zeta Potential gives an indication of the charge present on the particles surface. So if you obtained a positive value, this means that your particles are positive charged.

And usually a high ZP value (ca. +/- 35mV) indicates a big stability of the particles in solution.

O thanks a lot

Good question. Thank you for raising this question.

Thanks

The zeta potential is a key indicator of the stability of colloidal dispersions. ... So, colloids with high zeta potential(negative or positive) are electrically stabilized while colloids with low zeta potentials tend to coagulate or flocculate.
