Cold plasma can kill 99.9% of airborne viruses, U-M study shows
Dangerous airborne viruses are rendered harmless on-the-fly when exposed to energetic, charged fragments of air molecules, University of Michigan researchers have shown. They hope to one day harness this capability to replace a century-old device: the surgical mask. The U-M engineers have measured the virus-killing speed and effectiveness of nonthermal plasmas—the ionized, or charged, particles that form around electrical discharges such as sparks.
