Colloidal Silver is nano technology at work. Used by NASA in the space shuttle’s water filtration system, ionic silver has spanned the centuries. For thousands of years silver has been used as a healing agent by civilizations throughout the world. Its medicinal, preservative, and restorative powers can be traced as far back as the ancient Greek and Roman Empires. The perfect (spray bottle) companion for someone on the go. Spray on any surface, your face and hand and even inhale to disinfect any surface. Silver ions (ATOMS with an empty valence electron) are several nanometers to micrometers in diameter and coalesce as masses of islands suspended in water with the ability to destroy pathogens on contact. These silver ions are suspended in water and are not dissolved, ready for use.
