Key Points

  • Nanoceria-based, long-lasting Rapid Acting Disinfectant (RAD) Spray
  • Can curb transmission of COVID-19 via contact with surfaces
  • Safely disinfects for days after initially applied


The University of Central Florida invention is a nanoceria-based solution for disinfectant use. Rapid Acting Disinfectant (RAD) Spray is a solution that can curb transmission of COVID-19 via contact with surfaces in a manner that is not currently available and is unique as a disinfectant spray and temporary film. Early studies have shown that these viruses can live between two to three days on most common types of surfaces. Most known available disinfectants, while able to neutralize many types of viruses, usually require a reaction time on the order of 30 seconds to 10 minutes.

After application, the proposed RAD Spray has the unique ability to create a temporary, continually disinfecting film left behind on the surface to which it was applied. The persistent disinfectant activity is due to the regenerative (catalytic) properties of Ceria Nanoparticles (CNP) nano-surface reaction sites, which allow for continued disinfection of a surface when new viruses come into contact with it. For surfaces where a permanent disinfectant film is not easily applied, this presents an attractive solution.
