As scientists across the world continue to work on finding ways to contain the spread of COVID-19 pandemic, researchers are developing antiviral masks that may kill the deadly virus within one hour. Scientists are working with an anti-viral coating technology called DiOX, which uses organic disinfectant compounds in the textiles.

"The antiviral agent within the coating of the mask kills the virus by breaching its protective outer membrane, which is known as its envelope. Unlike other parts of the virus, the membrane remains the same regardless of any type of mutation. Hence this way of attacking the pathogen will work on any new variant of coronavirus," Dr Graham Christie, senior lecturer at the Department of Chemical Engineering and Biotechnology at the University of Cambridge, told.

"In fact, you could mutate the entire genome of the virus and it would have no effect on the envelope. We expect to see the same response regardless of the strain of coronavirus because structurally they are all very similar," he said.

The DiOX technology is based on quaternary ammonium salts - organic compounds widely used in the textile industry. Tests showed that the mask killed 95 percent of pathogens on its surface within one hour. After four hours, they were undetectable. The action of the antiviral agent continues to work because it is unaffected by changes in the spike protein of the virus.

Better than vaccines may be or at least in addition to vaccines .
