New research: Graphene mask inactivates coronaviruses under sunlight

Graphene is known for anti-bacterial properties. The researchers created a laser-induced form of graphene and tested it on E coli. It showed anti-bacterial efficiency of about 82 per cent. Most of the E coli were dead after 8 hours.

Initial tests on two human coronavirus species showed the graphene inactivated over 90 per cent of the virus in five minutes and almost 100 per cent in 10 minutes under sunlight.

The team also plans to test the graphene on the Covid-19 virus.
