A versatile DNA nanomachine detection system has been developed via the combination of DNAzyme with catalytic hairpin assembly (CHA) technology for achieving accurate and sensitive detection of lead ions (Pb 2+ ). In the presence of target Pb 2+ , capture DNA nanomachine formed by AuNP and DNAzyme r...
