What is graphene?
Graphene is extracted from graphite and is made up of pure carbon.
It is 200 times more resistant than steel and five times lighter than aluminum.
It conducts electricity better than any other material at room temperature.
It is thought that graphene could boost the useful life of batteries by 10 per cent.
Graphene can also detect cancer cells in the early stages of the disease.
The material was first discovered when Andre Geim and Konstantin Novoselov were 'playing' with graphite at the University of Manchester in 2004.
