Selectivity of DNAzyme-AgNCs based detection system. The degree of signal enhancement is defined as (FI-F0)/F0, where F0 and FI are the fluorescence intensities at 635 nm in the absence and presence of Pb2+ and other kinds of metal ions, respectively. The concentrations for Pb2+ and Cu2+ ions were 1 μM, and 1 mM for other metal ions.
