NPG combined with GR–5DNAzyme and AQDS created simple detection strategy. An anionic intercalator was used as indicator for lead ions detection. The mechanism of the GR–5DNAzyme–based electrochemical sensor was revealed. The sensor showed a promising potential for the detecting of Pb2+ in real sample.
