Since it was discovered in the UK in 2004, graphene—a single layer of carbon atoms tightly bound in a hexagonal honeycomb lattice—has been used in an ever-growing number of applications. Now scientists at City University of Hong Kong (CityU) have used the so-called “wonder material” to develop an antibacterial face mask which has the potential to combat Covid-19 quickly, cheaply and sustainably.
The findings were published in scientific journal ACS Nano. Used the world over, ordinary surgical face masks are an important way of stopping the spread of Covid-19. However, viral particles can still settle and survive on such masks, which means that if they are touched or disposed of inappropriately, they can still cause infection.
