Ce-Doped and Defect-Engineered Zr-Based MOF Nanozyme with Enhanced Organophosphorus Hydrolase-like Activity for Detoxification and the Dual-Mode Detection of Nerve Agent Simulants

(ZrCe) through the inner filter effect. This sensor exhibited a wide detection range (0.4-90 μM) and a low detection limit (0.185 μM). Furthermore, a smartphone-integrated portable platform was well established to enable simple, rapid, and efficient detection of DMNP, thus holding great potential in practical applications for the decontamination and identification of nerve agents.
