BCNO nanoparticles: A novel highly efficient fluorosensor for ultrarapid detection of Cu2+

In this paper, we demonstrate the first use of BCNO nanoparticles (BCNO NPs) as a novel highly efficient fluorosensor for Cu2+ detection with high selectivity. The detection process is ultrafast and can be completed within 2 min, and the detection limit is 0.1 μM. We also show the practical use of this sensor for Cu2+ determination in real water samples.
