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.
