ChemistrySelect, Journal Year: 2025, Volume and Issue: 10(8)

Published: Feb. 1, 2025

Abstract Metronidazole (MET) detection in the human body is essential for monitoring therapeutic levels, ensuring accurate dosage, and preventing toxicity or treatment failure. To facilitate this, an electrochemical (EC) sensor developed by modifying a glassy carbon electrode (GCE) with chitosan (CS) silver nanoparticles. Silver nanoparticles are synthesized using environmentally friendly green method, involving tea ( Camellia sinensis ) leaf extract under microwave irradiation. These combined biodegradable electroactive natural polymer CS to enhance analytical performance of sensor. Cyclic voltammetry analysis modified reveals enhanced reduction peak MET at −0.397 V, maximum current −0.264 mA observed pH 1. The EC reaction controlled both diffusion adsorption processes. demonstrates linear response concentrations ranging from 0.1 1244 µ M, limit 0.597 nM. Additionally, it exhibits impressive stability during repeated scans extended time periods, while its sensitivity thoroughly evaluated through real sample analyses.
