Colloidal Silver


Nano colloidal silver has a wide range of application in various industries. Including: Antimicrobial and antibacterial properties on the surface of medical equipment, in the food packaging industry and in polymers and clothing fibers. Optic usage (like solar cells), conduction (such as conductive adhesives and touch plates), and chemical (catalysts) are of the other important applications of these nanomaterial.

-HIGH ELECTRICAL CONDUCTIVITY -HIGH THERMAL CONDUCTIVITY -ANTIBACTERIALS -SURFACE PLASMA RESONANCE -Silver particles are stabilized easily in nano-dimension which leads to formation more stable colloids. The most noticeable advantages of silver nanoparticles are in biomedicine. It could be mentioned that in nano-dimension, antibacterial effect of silver increases significantly, so that they are able to destroy over 650 bacterial species. These nanoparticles have significant antifungal activities against some ringworms. Silver nanoparticles disrupt fungal structure and cause significant damage to fungal cells. It is also demonstrated the cytoprotective activity of silver nanoparticles (5-20 nm) toward HIV-1 infected cells. The modified electrochemical properties of silver nanoparticles can also offer faster response times and lower detection limits in nano-scale sensors.

Manufacturer's Description

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.
