The new developed coating when painted on glass or stainless steel, reduces the amount of SARS-CoV-2 virus by 99.9 per cent in one hour, compared to the uncoated sample, say researchers.

Coronaviruses infect animals, humans, and birds. Human coronaviruses, such as SARS, MERS, and 2019-nCoV cause respiratory distress and even death. The S protein is the infectious agent of the virus.

"The idea is when the droplets land on a solid object, the virus within the droplets will be inactivated," said study researcher William Ducker from Virginia Polytechnic Institute and State University in the US. "One hour is the shortest period that we have tested so far, and tests at shorter periods are ongoing," Ducker added.
"We have to use our chemical knowledge and experience of other viruses to guess what would kill it (SARS-CoV-2)," the study author wrote.

Now, the research team hopes to attract funding in order to mass-produce the coating film.
"To be sure, the film doesn't replace other safety measures that people should take to stop the spread of the coronavirus, such as hand washing, physical distancing, and wearing a mask," the study author wrote.
"People won't have to worry as much about touching objects, it will be both practical and reducing fear," they noted.
