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,… read more here.
