Copper-infused face mask claims to kill 90% of coronavirus particles

A new copper-infused face mask claims to kill 90 per cent of coronavirus particles.

A scientist at Nottingham Trent University has developed the five layer mask, which includes a hypoallergenic hydrophilic layer, which is positioned closest to the face, followed by two filter layers sandwiched around an anti-viral nano tech layer. The final layer is a fluid repellent layer.

Dr Gareth Cave, a nanotechnology expert, are hoping they will be available commercially in December.

He said: "It's exciting to see our technology move forward and make a real impact towards the fight against the spread of COVID-19. The mask we've developed has been proven to inactivate viruses upon contact; the antiviral layer kills virus which has been blocked by the filter layers.

"The challenge with conventional surgical-type masks is that they only block virus from entering or exiting the mask. They don't have an active mechanism for killing it once it's trapped in the mask. Our new antiviral mask has been designed to utilise the existing barrier technology and combine it with our nanotechnology to kill the virus once it is trapped there.

"We've added the barrier layer to both sides of the mask so not only does it protect the wearer but also those around. By killing the virus on contact, it also means that the used face mask can be safely disposed of and not be a potential source of passive transfer."
