title: A DNAzyme cascade for the amplified detection of Pb(2+) ions or L-histidine.
abstract: DNAzyme cascades activated by Pb(2+)- or L-histidine-dependent DNAzymes yield the horseradish peroxidase-mimicking catalytic nucleic acids that enable the colorimetric or chemiluminescence detection of Pb(2+) or L-histidine.
