Graphene has been one of the most talked-about discoveries in the last decade.
Its strength, flexibility and conductivity make it a potentially ideal material for bendable smartphones and superior prosthetic limbs.
But graphene has another, less-heralded property which could help it transform the everyday lives of people around the world.
Despite being just one atom thick, it is impervious to almost all liquids and gases.
Generating holes in sheets of graphene could therefore create a selective membrane - “the ultimate water purifier” - which might someday create drinking water from the sea.
