A highly sensitive and selective electrochemical biosensor for Pb

with a dual-amplification strategy is proposed. The first amplification step was realized by the cycle of Pb

and 8–17 DNAzyme (S2), and the hybridization chain reaction (HCR) triggered by S1 further amplified the electrochemical signal. Fe
