Further, due to the presence of high surface area, and a rich oxygen and defect framework, they are able to form nanocomposites with metal/semiconductor nanoparticles, metal oxides, quantum dots and polymers. Such nanocomposites are becoming increasingly useful as electrochemical biosensing platforms. In this review, we present a brief introduction on the aforementioned graphene derivatives, and discuss their synthetic strategies and structure-property relationships important for biosensing. We then highlight different nanocomposite platforms that have been developed for electrochemical biosensing, introducing enzymatic biosensors, followed by non-enzymatic biosensors and immunosensors. Additionally, we briefly discuss their role in the emerging field of biomedical cell capture. Finally, a brief outlook on these topics is presented.Biochemistry & Molecular BiologyChemistry, MultidisciplinaryChemistrygraphenegraphene oxidereduced graphene oxideelectrochemical biosensorcell capturesensitive nonenzymatic glucosehybridization chain-reactionzinc superoxide-dismutasebreast-cancer biomarkersglassy-carbon electrodereduced graphenethermal reductiondrug-deliverydna biosensorquantum dotstext::journal::journal article::review article
