Abstract

A novel strategy was proposed for the determination of Hg2+ in water, foods, and living organisms based on the quenching and recovery of the fluorescence of CDs-ssDNA through the FRET process induced by AuNPs-cDNA. The results showed a wide response range, pM detection limit, and high selectivity.
