title: A sensitive and specific electrochemiluminescent sensor for lead based on DNAzyme.
abstract: A specific ECL sensor for Pb2+ based on DNAzyme has been developed for the first time; the detection limit of 1.1 x 10(-11) mol l(-1) is much lower than those of fluorescent, colorimetric or electrical biosensors.
