Graphene–DNAzyme Based Biosensor for Amplified Fluorescence “Turn-On” Detection of Pb2+ with a High Selectivity

On the basis of the remarkable difference in affinity of graphene (GO) with ssDNA containing a different number of bases in length, we for the first time report a GO–DNAzyme based biosensor for amplified fluorescence “turn-on” detection of Pb2+. A FAM-labeled DNAzyme–substrate hybrid acted as both a...
