title: Label-free fluorescent detection of Cu(II) ions based on DNA cleavage-dependent graphene-quenched DNAzymes.
abstract: We developed a novel and general methodology to design a label-free fluorescent Cu(II) sensor based on internal DNA cleavage and an extrinsic fluorophore in a graphene/DNAzymes complex with high sensitivity and selectivity.
