A “turn-off” SERS aptasensor based DNAzyme-gold nanorod for ultrasensitive lead ion detection
It is great significance to precisely monitor lead (II) ions (Pb(2+)) for environment protection and human health monitoring. We designed a sensitive detection strategy for sensitive and selective determination of Pb(2+), based on a Pb(2+)-specific DNAzyme as the catalytic unit, Cy3-labeled DNA modi...
