Dual-emissive EY/UiO-66-NH2 as a ratiometric probe for turn-on sensing and cell imaging of hypochlorite

EY/UiO-66-NH 2 could be used as a self-calibrating nanoprobe for the detection of ClO − , which exhibits a wide linear range 0.1–200 μM and a low detection limit 46.4 nM. The content of EY is important to the ratiometric fluorescence of the probe.
