中文摘要herein, we report a new kind of highly fluorescent probe for cu2+ sensing generated by hydrothermal treatment of graphene quantum dots (gqds). after hydrothermal treatment in ammonia, the greenish-yellow fluorescent gqds (ggqds) with a low quantum yield (qy, 2.5%) are converted to amino-functionalized gqds (afgqds) with a high qy (16.4%). due to the fact that cu2+ ions have a higher binding affinity and faster chelating kinetics with n and o on the surface of afgqds than other transition-metal ions, the selectivity of afgqds for cu2+ is much higher than that of ggqds. furthermore, afgqds are biocompatible and eco-friendly, and the afgqds with a positive charge can be easily taken up by cells, which makes it possible to sense cu2+ in living cells. the strategy presented here is simple in design, economical, and offers a mix-and-detect protocol without dye-modified oligonucleotides or complex chemical modification.
