Reversible molecular switching of molecular beacon: controlling DNA hybridization kinetics and thermodynamics using mercury(II) ions

Author affiliations

Abstract

We report that the hydrogen-bonding pattern in a molecular beacon can be replaced by metal-dependent pairs of Hg2+ and DNA thymine (T) bases. A molecular beacon based on T–Hg2+–T exhibits a lower background signal and higher thermostability than regular molecular beacons.
