Abstract
tA facile strategy has been developed to fabricate silver nanoparticles (Ag NPs) through an electrochemicalmethod with the assistance of metformin functionalized MWCNT (Ag@MH/MWCNT nanocomposite).Investigations by field emission scanning electron microscopy (FESEM) confirmed that the preparednanocomposite have a porous structure that is constructed by interconnecting functionalized MWCNTframework. Electrochemical studies show that the nanocomposite exhibits high stability and excellentactivity for electrocatalytic oxidation of glucose in alkaline solutions, which allows the Ag@MH/MWCNTto be used in enzyme-free amperometric sensors for glucose determination. It was confirmed that theAg@MH/MWCNT based glucose biosensor presents wide response window for glucose concentrations of1.0 nM–350 M, short amperometric response time (4 s), low detection limit of 0.0003 M (S/N = 3), highsensitivity as well as good selectivity.
