When NanoShield is applied, quadrillions of particles entirely coats a surface at a sub-microscopic level and absorbs the light. By absorbing the light, a photocatalytic action happens: Creates HYDROXYL RADICALS. These radicals are the fastest reacting natural shredders of 99.999% viruses, bacteria, and mold. It is not new, there is a Nobel prize awarded around Hydroxyl Radicals as the detergent in the atmosphere. The clean experience is like spreading hydrogen peroxide across all surfaces multiple times per second every day for a year.
