A Graphene Oxide Based Immuno‐biosensor for Pathogen Detection

Don′t FRET when I GO: Sensitive and selective rotavirus detection is achieved by using the photoluminescence of a graphene oxide (GO) array. The target cell was captured by the rotavirus-specific antibody immobilized on the GO array, and the binding event was monitored by observing the fluorescence quenching that results from fluorescence resonance energy transfer (FRET) between GO and gold nanoparticles linked to the antibodies (see picture).
