Photothermal-driven magnetic ZnFe2O4 "three-in-one" nanoplatform for interfacial enrichment and rapid screening of 3-monochloropropane-1,2-diol in edible oils.
Detection of 3-MCPD in lipid-rich food matrices remains challenging due to trace analyte levels, high viscosity, and severe matrix interference. Herein, a photothermal-driven magnetic "three-in-one" sensing platform based on L-cysteine-functionalized ZnFe2O4 (L-ZFO) nanoparticles was developed for rapid and sensitive s...
