- 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.
