Ultrasensitive detection of lead ions based on a DNA-labelled DNAzyme sensor

Here, we report a facile approach for highly sensitive and selective detection of aqueous lead ions that uses a real-time quantitative polymerase chain reaction technology and a lead-dependent DNAzyme, termed GR-5. In this method, the substrate DNA is cleaved at the site of the adenosine ribonucleot...
