Graphene quantum dots (GQDs)-based nanohybrid materials have gained great attention in multiple research applications, particularly in biomedical fields due to their unique physicochemical properties and outstanding biocompatibility compared to other nanomaterials. In this review, we focus on the most recent emerging developments including synthesis methods, in vivo imaging and in vitro biosensing applications. We also discuss these unresolved problematic and controversial issues facing their biomedical applications. Consequently, trends in approaches to improve the analytical performance of GQDs-based nanomaterials have also been put forward. Keywords: Graphene quantum dots (GQDs), Immunosensors, Imaging, Drug delivery, Toxicity
