Graphene-based nanomaterials for drug and/or gene delivery, bioimaging, and tissue engineering

Here, we discuss the biomedical applications of graphene-based nanomaterials (GBNs). We examine graphene and its various derivatives, including graphene, graphene oxides (GOs), reduced graphene oxides (rGOs), graphene quantum dots (GQDs), and graphene composites, and discuss their unique properties related to their biomedical applications. We also summarize the detailed biomedical applications of GBNs, including drug and/or gene delivery, bioimaging, and tissue engineering. We also highlight the toxicity of these nanomaterials.
