Chemical functionalization of graphene oxide (GO) fixed on a solid substrate is a topic of paramount importance, for it allows fine-tuning of the chemical and physical properties of GO.In this study, we demonstrate that the substrate influences the reactivity of the top surface of GO using quantitative reactions with fluorescent dyes.In summary, we demonstrate that the reactivity of GO films on the solid substrate is strongly influenced by the morphology of GO which is determined by wettability.
