A catalytic beacon sensor for uranium with parts-per-trillion sensitivity and millionfold selectivity
Here, we report a catalytic beacon sensor for uranyl (UO(2)(2+)) based on an in vitro-selected UO(2)(2+)-specific DNAzyme. The sensor consists of a DNA enzyme strand with a 3′ quencher and a DNA substrate with a ribonucleotide adenosine (rA) in the middle and a fluorophore and a quencher at the 5′ a...
