Nano-silica, is a silicon oxide (SiO2) nanoparticle that is synthesized as a completely pure nanostructured containing nano-cavities on its surface. Nanosilica is one of the most widely used nanomaterials in the world of nanopowders. It has many applications as reinforcement, concentrator, anti-blocking and anti-caking (anti agglomeration).
Colloid is a state of matter between solution and suspension that a non-dissolving component is suspended in another component and is stabillized by methods such as electrostatic stabilization and steric stabilization. Nano colloidal silver is a suspension contains nanometer sized silver particles in a certain solution.
