Graphene Biosensors

A biosensor is a device which measures biological or chemical reactions by creating an electrical output response that is proportional to the concentration of a particular substance (or analyte) within that reaction. They are used in a wide range of areas including medical treatment, environmental surveys, food control, forensics and...

Graphene field-effect transistor (GFET) photodetectors

A surprising application of graphene is its use in photodetectors. Light detection capabilities of graphene are inherently limited because a single sheet of the material absorbs only ~2.3% of light across the visible part of the spectrum. Such high transparency is desired for applications such as transparent conductors, however detecting...
