A straightforward green fabrication of electrochemical assay for high sensitive quantitative detection of methyl parathion (organophosphate pesticide) via colloidal gold nanoparticles (AuNPs) modified glassy carbon electrode. Methyl parathion is widely known for its unpleasant functions in bio and ecological system. The synthesis utilizes tannic acid as a bi-functional reducing cum stabilizing agent under ambient temperature (25 °C). The colloidal TA@AuNPs were characterized through TEM, UV–vis, X-ray diffraction, and FT-IR spectroscopy. Fabricated TA@AuNPs/GCE assay has superior electrocatalytic activity toward MP in terms of a wide dynamic range (0.033–167.7 µM), and lower limit of detection (10.5 nM). In addition, the sensor displayed high selectivity, good reproducibility and stability. The practicality of fabricated electrode was verified through the determination of MP in various food and water samples. [ABSTRACT FROM AUTHOR] |
