Can Ultraviolet Light Kill Aerosolised Coronavirus? Scientists May Finally Have an Answer

News 18  

New research adds to the growing body of evidence that ultraviolet C lighting can be a new solution to kill aerosolised Covid-19 in enclosed environments such as hospitals and long-term care facilities. Computational modelling has shown that low dose far-ultraviolet C lighting can be used to disinfect in-room air, increasing disinfection rates by 50-85 per cent compared to a room’s ventilation alone, the study published in the journal Scientific Reports, reported. “In indoor environments where it may not be possible to socially distance, aerosolised coronavirus released through breathing increases the chance of spreading the disease,” said study author Liang Yang from the Cranfield University in the UK. “Far-UVC is safe because it has the unique property of interacting more readily than lower wavelength UVC but is not energetic enough to reach living human cells,” the authors wrote.

Novel plastic film can kill Covid virus using just room light

India TV News  

Highlights The film is coated with a thin layer of particles that absorb ultraviolet light. The technology used to create the film also ensures it is degradable -- unlike the current disposable plastic films -- making it environment-friendly, the researchers said. The researchers tested the film for anti-viral activity using four different viruses -- two strains of influenza A virus, …
