title: "Molecular beacon"-directed fluorescence of Hoechst dyes for visual detection of Hg(II) and biothiols and its application for a logic gate.
abstract: A molecular beacon (MB)-like DNA hairpin biosensor based on the reversible directing fluorescence of Hoechst dyes was developed for fluorescent detection of Hg(2+) and biothiols and furthermore for logic operation.
