Abstract

The turn-on fluorescence of pyrophosphate anion (PPi) was detected using DNA-attached cobalt oxyhydroxide. The fluorescence signal was quenched when carboxyfluorescein-labeled ssDNA was adsorbed by CoOOH nanoflakes through electrostatic interaction. With the addition of target PPi, PPi competed with DNA for CoOOH nanoflakes, resulting in turn-on fluorescence.
