(Invited) Fluorescence and Sensing Applications of Graphene Oxides

First, the florescence emission mechanism of graphene oxide will be discussed. Second, fluorescence of graphene oxide can be tuned by tailoring functional groups. Third, graphene oxide-based sensors can be designed with graphene oxide either as an energy donor or as an energy acceptor. Fourth, graphene oxide-based sensors have been sued to detect heavy metal and biomarkers.
