A highly selective lead sensor based on a classic lead DNAzyme.

ABSTRACT: A catalytic beacon sensor for Pb(2+) has been developed based on the first DNAzyme discovered in the field, and such a sensor has shown a much higher metal ion selectivity (40,000 times) than the previously reported Pb(2+) sensor based on 8-17 DNAzyme and thus is suitable for a wider range of practical applications.
