Abstract

This study reports the handheld detection of four pesticide residues (acephate, carbendazim, thiamethoxam, and tricyclazole) in Basmati rice using surface-enhanced Raman spectroscopy (SERS). Different SERS substrates were synthesized and evaluated. Detection limits in solvent ranged from 5 ppb to 75 ppb. QuEChERs acetate extraction was used to recover pesticide residues from rice. This method improved detection limits within the matrix, enabling detection of three out of four pesticides below the Maximum Residue Limits (MRLs) of 10 ppb. The multiplexing performance of handheld-SERS was also assessed. The study demonstrates the potential of handheld-SERS for rapid, on-site pesticide residue detection.
