Three way sensing on a single graphene Biosensor

A biosensor is a device that uses a living organism or biological molecules, especially enzymes or antibodies, to detect the presence of chemicals

The team led by Ertugrul Cubukcu assistant professor in the departments of Materials Science and Engineering and Electrical and Systems Engineering in Penn ’s School of Engineering and Applied Science  has just invented the a biosensor in an unlikely and least expected setting that can work in three ways at once.  The graphene based biosensor can act as utilize plasmonic, mechanical resonance and field effect transistor to give results for three different stimuli.

The study has been published in the journal NanoLetters.
