Fluorescence Sensor Based on Methionine-Modified Silver Nanoparticles Embedded in Fe-BTC metal-organic framework (Meth-AgNPs@Fe-BTC) for Trace Detection of FenitrothionPesticide in Aqueous Samples

In this research paper, a new "On-mode" fluorescence sensor has been introduced for detectingfenitrothion (FNT) pesticide in various samples. This sensor consists of a Fe-BTC metal-organic framework (MOF)as a porous template for embedding methionine-modified silver nanoparticles (Meth-AgNPs@Fe-BTC).Physicochemical properties of the synthesized Meth-AgNPs@Fe-BTC composite were characterized usingFourier-transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), Field emission scanning electronmicroscopy (FESEM), Energy-dispersive X-ray spectroscopy (EDAX), Transmission electron microscopy (TEM),and element mapping (MAP) analysis. It works based on tracking the fluorescence of the synthetic composite insuch a way that the intensity of the fluorescence of the composite increases in the presence of differentconcentrations of fenitrothion (FNT).
