An all-in-one Zn/Ce-MOF nanozyme: combining ratiometric sensing, oxidase-like activity, and apparent phosphoester hydrolase-like behavior for organophosphorus pesticide monitoring.
The widespread residue of highly toxic organophosphorus pesticides (OPs) poses a serious threat to food safety and human health, underscoring the need for sensitive screening methods. In this work, a ratiometric fluorescence sensor array was constructed based on a trifunctional Zn/Ce-MOF exhibiting intrinsic blue fluor...
