title: Enzyme-free strip biosensor for amplified detection of Pb2+ based on a catalytic DNA circuit.
abstract: A simple and enzyme-free strip biosensor for the amplified detection of Pb(2+) has been constructed based on a catalytic DNA circuit. This assay is ultrasensitive, enabling the visual detection of Pb(2+) concentrations as low as 10 pM without instrumentation.
