The one-atom-thick substance graphene can now be used to detect molecules in the human body. Graphene, which is a form of carbon that's only one atom thick, has been hailed as a "miracle substance" for its incredible strength and ability to conduct electricity and heat.

Scientists have now developed a way to use graphene as a sensor in the body. They "tuned" the graphene to different frequencies to attract different types of proteins or drug molecules within the body. The molecules are then analyzed using infrared light. 

This technology could contribute to medication monitoring devices for patients with diabetes or cancer and a provide a newly accurate way of sensing pollutants in our environment and bodies. 


facts about graphene: 

 One of the myriad possible uses for graphene is super-fast computing. It's possible graphene-based antenna could allow for uploading a terabit of data in one second. 

 Graphene could help attract radioactive waste, helping to clean up water near sites like Fukushima. 

 Say goodbye to broken phone screens: graphene may allow us to build touch screens made of plastic instead of glass.
