| Description |
In this work,we report the detection of organophosphorous pesticides, particularlymethyl parathion using gold
atomic clusters (AuACs) non-enzymatically employing squarewave voltammetry (SWV). Synthesis of surfactant
stabilized gold atomic clusters on a polycrystalline gold electrode was executed by a simple potentiodynamic
cyclic voltammetry technique. The clusters are characterized using UV–visible spectroscopy and transmission
electron microscopy techniques. The electroanalytical results exhibited linear behavior in the micro (10–80 μM)
as well as nanomolar (1–10 nM) concentration ranges and the detection limit is found to be 0.65 nM (S/N=3).
The proposed sensor matrix is evaluated with real samples and the results are in good agreement with high
performance liquid chromatographic (HPLC) analysis.
