If you have ever drawn with a pencil, you have probably made graphene.

Although sporadic attempts to study graphene can be traced back to 1859, there has been an explosion in research around the material since 2004, when Professor Sir Andre Geim and Professor Sir Kostya Novoselov of the University of Manchester discovered and isolated a single atomic layer of carbon for the first time. The pair received the Nobel Prize in Physics in 2010 in recognition of their breakthrough.
The ‘Scotch tape method’ used at Manchester was so simple and effective that this area of science grew extremely quickly, and now hundreds of laboratories around the world deal with different aspects of graphene research. Also known as the micromechanical cleavage technique, the Scotch tape method does not require large investments or complicated equipment, which has helped to broaden the geography of graphene science considerably.
