Gold covered with graphene is arranged in an array
Writing , the scientists, working with colleagues from Aix-Marseille University , have created a device which potentially can see one molecule though a simple optical system and can analyse its components within minutes. This uses plasmonics - the study of vibrations of electrons in different materials. The breakthrough could allow for rapid and more accurate drug testing for professional athletes as it could detect the presence of even trace amounts of a substance. It could also be used at airports or other high-security locations to prevent would-be terrorists from concealing explosives or traffickers from smuggling drugs. Another possible use could be detecting viruses people might be suffering from. Graphene, isolated for the first time at The University of Manchester in 2004, has the potential to revolutionise diverse applications from smartphones and ultrafast broadband to drug delivery and computer chips. It has the potential to replace existing materials, such as silicon, but University of Manchester researchers believe it could truly find its place with new devices and materials yet to be invented.
