title: A novel electrochemical DNAzyme sensor for the amplified detection of Pb2+ ions.
abstract: A novel amplification strategy based on DNAzyme functionalized gold nanoparticles was employed to enhance the sensitivity of an electrochemical sensor for detection of Pb2+. The detection limit is 0.028 nM, which is much lower than for other electrochemical DNAzyme sensors.
