“Off-On” non-enzymatic sensor for malathion detection based on fluorescence resonance energy transfer between β-cyclodextrin@Ag and fluorescent probe
Özet
© 2018Here, we developed a novel non-enzymatic rapid testing method for determination of organophosphate pesticide (malathion) in water. In principle, target molecule can block the Fluorescence resonance energy transfer (FRET) between chemical fluorescent probe (energy donor) and β-cyclodextrin-coated silver nanoparticles (@AgNP) (receptor). The effects of malathion on the dynamics of fluorescent probe and β-cyclodextrin@AgNP were evaluated and their properties were further characterized. The current methodology showed a good sensitivity of 0.01 μg/mL represented as a limit of detection (LOD) and the calibration curve was linear over the concentration range of 0.1–25 μg/mL. Recovery rate from water samples spiked at 3 different concentration levels (0.3, 0.4, and 0.6 μg/mL) showed satisfactory range between 83% and 101%.
