Smart Silver by Desbio uses a special form of patented nano-silver that gives it many unique qualities other forms of silver do not have. DesBio’s nano-silver is made of a metallic core that is coated with a layer of tetra silver - tetra oxide molecules (AG4O4). Smart silver by Desbio is an engineered nanoparticle, not a colloidal silver. It is manufactured using 10,000 volts of current, energizing the entire waterbase, enabling Smart Silver to work as a catalyst to kill bacteria as it draws energy from its environment and emits energy at wavelengths that are measured at 890 to 910 terahertz. This is the same frequency at which germicidal ultraviolet light resonates and is deadly to bacteria. Therefore, Smart Silver, due to the patented revolutionary process of its manufacture, does not deal with bacteria on merely a chemical level, as do colloidal silvers, but also works on a measurable energetic level. Liquid is is 10 ppm and gel is 24 ppm
