Systematic Nonenzymatic Glucose Detection Using Hydrogel-Protected Ag-Cu/MWCNTs Nanocomposites.

ABSTRACT: The growing need for reliable and selective glucose monitoring has accelerated interest in nonenzymatic electrochemical sensors. In this work, we introduce a high-performance sensor based on silver-copper (Ag-Cu) alloy nanoparticles uniformly anchored onto multiwalled carbon nanotubes (MWCNTs), further enhanced with a polymeric protective layer composed of polyvinylpyrrolidone (PVP) and poly-(vinyl alcohol) (PVA). The materials were synthesized via a hydrothermal process, and the atomic ratio of Ag/Cu was precisely tuned. Among all compositions, the Ag₅-Cu₅ configuration exhibited the highest electrocatalytic activity, attributed to a strong bimetallic synergistic effect and the excellent conductivity of the MWCNTs framework.
