Provided are devices and methods featuring a nanoelectronic interface between graphene devices (for example, field effect transistors or FETs) and biomolecules such as proteins, which in turn provides a pathway for production of bioelectronic devices that combine functionalities of the biomolecular and inorganic components. In one exemplary application, one may functionalize graphene FETs with fluorescent proteins to yield hybrids that respond to light at wavelengths defined by the optical absorption spectrum of the protein. The devices may also include graphene in electronic communication with a biomolecule that preferentially binds to a particular analyte.

Graphene-biomolecule bioelectronic devices

The present invention provides a broad response single-stranded DNA-graphene chemical sensor device. The present invention also provides methods for improving the ability of graphene to work as a chemical sensor by using single-stranded DNA as a sensitizing agent.
