Biosensors, which are analysis devices used to convert biological reactions into electric signals, are made up of a receptorcomponent and a signal transduction part. Graphene quantum dots (GQDs) and carbon quantum dots (CQDs) are new types ofcarbon nanoparticles that have drawn a significant amount of attention in nanoparticle research. The unique features exhibited byGQDs and CQDs are their excellent fluorescence, biocompatibility, and low cytotoxicity. As a result of these features, carbonnanomaterials have been extensively studied in bioengineering, including biosensing and bioimaging. It is extremely importantto find biomaterials that participate in biological processes. Biomaterials have been studied in the development of fluorescencebaseddetection methods. This review provides an overview of recent advances and new trends in the area of biosensors based onGQDs and CQDs as biosensor platforms for the detection of biomaterials using fluorescence. The sensing methods are classifiedbased on the types of biomaterials, including nucleic acids, vitamins, amino acids, and glucose. KCI Citation Count: 0
