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. Due to the geometry of silver particles that have a high surface-to-volume ratio, as well as the nature of silver element which is anti-bacterial, it is disinfectative in preventing bacterial growth. This material is also beneficial in the electrical and thermal industries. In some countries, nano colloidal silver is useful as dietary supplements. Silver is scentless and innocuous and hence can be safely used for persons with sensitive skin. Application of this material varies according to the size, shape and concentration of silver particles.
