Anupconversion fluorescence sensing platform was developedwith upconversion nanoparticles (UCNPs) as energy donors and gold nanoparticles (AuNPs) as energy acceptors, based on the FRET principle. They were used for quantitativedetection ofuranyl ions (UO(2)(2+)) by amplifying the signal of the hybrid chain reaction (HCR). When UO(2)(2+) are introduced, the FRET between AuNPs and UCNPs can be modulated through a HCR in the presence of high concentrations of sodium chloride. This platform providesexceptional sensitivity, with a detection limit as low as 68pM for UO(2)(2+) recognition. We have su...
