Abstract EN
In this study, an ultrasensitive detection method for aqueous Pb2+ based on digital polymerase chain reaction (dPCR) technology and a Pb2+-dependent DNAzyme was developed.
In the presence of Pb2+, the Gr-5 DNAzyme was activated and catalyzed the hydrolytic cleavage of the substrate strand, resulting in an increase in the amount of template DNA available for dPCR and a resultant change in the number of droplets showing a positive signal.
Moreover, the detection system was found to be sensitive and stable in environmental sample detection.
In summary, an ultrasensitive quantitative detection method for Pb2+ within environmental substrates was established.
