Researchers from the University of Swansea developed an ultra-sensitive biosensor based on graphene. According to the researchers, this sensor is more than five times more sensitive than bioassay tests currently in use.
The sensor is based on large-area graphene devices grown on silicon carbide. The graphene was later patterned and then attached to bioreceptor molecules. These molecules act as receptors and they bind to the target molecule.
