Eden Morales-Narvez, Abdel-Rahim Hassan, and Arben Merkoçi. Angwandte Chemie, Volume 52, Issue 51, December 16, 2013, pages 13779–13783

Turned ON by a pathogen: A highly sensitive pathogen-detection system has been designed and evaluated for the sensing of E. coli bacteria in diverse matrices. It employs antibody–quantum dot (Ab-QD) probes and exploits the extraordinary two-dimensional structure and fluorescence-quenching capabilities of graphene oxide.
