Miniaturized integrated electrochemical sensor using Ag@MoS2/graphene oxide aerogel for implantable non-enzymatic glucose monitoring

Year: 2025

Type: article

Abstract: In this study, a Ag@MoS₂/graphene oxide aerogel (GOA) nanocomposite was synthesized and used to fabricate a non-enzymatic glucose sensor. The sensor exhibited a wide linear range (1.0 to 10.0 mM), high sensitivity (546.37 nA mM⁻¹ cm⁻²), and a low detection limit (53.29 µM). The sensor's performance was significantly enhanced in an alkaline environment due to the presence of hydroxide ions, which facilitated glucose oxidation. The sensor also demonstrated excellent selectivity against common interferents and maintained high stability over 30 days. The synergistic effects of AgNPs, MoS₂ nanosheets, and GOA contributed to the sensor's superior electrochemical performance, making it a promising candidate for glucose sensing applications.
