Experimental study demonstrates reliable non-enzymatic detection of organophosphate and carbamate pesticides, highlighting an eco-friendly platform for chemical residue monitoring.

Key Points

Synthesize silver nanoparticles on a copper sulfide semiconductor using green synthesis to engineer a non-enzymatic electrochemical sensor for paraoxon-ethyl and carbaryl.
Synthesized silver/copper sulfide (Ag/CuS) composites across concentrations (0.10, 0.25, 0.50, 0.75, and 1.00 M) using tangerine orange peel extract as a reducing agent.
Fabricated modified screen-printed carbon electrodes using Ag/CuS combined with multi-walled carbon nanotubes and chitosan.
Characterized electrode conductivity using cyclic voltammetry and electrochemical impedance spectroscopy, and benchmarked pesticide quantification against high-performance liquid chromatography.
The electrode formulated with 0.75 M Ag/CuS, multi-walled carbon nanotubes, and chitosan demonstrated the highest electrical conductivity.
Cyclic voltammetry yielded a linear detection range of 5–30 ppm with determination coefficients (R²) of 0.95943 for paraoxon-ethyl and 0.99328 for carbaryl.
Comparative high-performance liquid chromatography confirmed linear detection profiles with R² values of 0.99957 for paraoxon-ethyl and 0.99992 for carbaryl.
