摘要：

A simple and environmentally friendly approach was developed to fabricate silver nanoparticle (Ag NP)-decorated porous reduced graphene oxide (grGO) using glucose as a crosslinking and reducing agent. Physicochemical analysis, such as X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), transmission electron microscopy (TEM), and field emission-scanning electron microscopy (FE-SEM) were used to confirm the structural, morphological characteristics of the as-prepared samples. The electrocatalytic activity of Ag/grGO towards glucose oxidation was examined by cyclic voltammetry and amperometry. The fabricated sensor showed excellent sensitivity of 725.0 mu A cm(-2) mM(-1) with a rapid response time of 11 s. Furthermore, the hybrids showed significant antibacterial activity against Escherichia coli with 99.76% antibacterial efficiency after 18 h.
