title: Pb(2+)-introduced activation of horseradish peroxidase (HRP)-mimicking DNAzyme.
abstract: A novel nucleic acid hairpin structure composed of Pb(2+)-dependent DNAzyme and HRP-mimicking DNAzyme was developed. This hairpin structure can be used as a sensor for the detection of Pb(2+) based on colorimetry.
