Mercury gauge: An oligodeoxyribonucleotide(ODN)-based sensor, which carries energy-donor and -acceptor moieties (fluorescein, F, and dabcyl, D, respectively), selectively detects HgII ions in aqueous solution. Upon binding HgII ions, the ODN takes on a hairpin structure (see picture); this results in a decrease in the fluorescence emission through enhanced FRET (fluorescence resonance energy transfer) from F to D.
