Abstract
Here, we demonstrated a Pb2+ detecting aptasensor using Pb2+-sensitive DNAzymeconjugated
gold nanorods (GNRs). Fluorescent DNA substrates that were initially quenched
by GNRs, are released in response to Pb2+ ions to give a substantial fluorescence signal.
The GNR-tethered DNAzyme is reusable at least three times with a LOD of 50 nM.
