摘要：Rhodamine B derivatives (RBP)-modified UCNPs (UCNPs@mSiO(2)-RBP) were developed as a fluorescent turn-off-on sensor based on FRET and IFE to detect Cu2+ and pyrophosphate (PPi) with a wide linear response range (0-10 mu M for Cu2+ and 5-35 mu M for PPi, much wider than that reported previously) and high sensibility (117 nM for Cu2+ and 70 nM for PPi). The MTT experiments and the bioimaging experiments show its promising prospect in tissue imaging.
