Bifunctional single-labelled oligonucleotide probe for detection of trace Ag(I) and Pb(II) based on cytosine-Ag(I)-cytosine mismatches and G-quadruplex

A novel bifunctional oligonucleotide (OND) probe with single fluorescent group HEX labelled at 5′-end was designed for detecting trace Ag(I) and Pb(II) in real samples. In the presence of Ag(I), the hairpin structure originating from Ag(I) induced cytosine-Ag(I)-cytosine mismatches causes the proxim...
