▎ 摘　　要

In this research work, non-enzymatic FET sensor using silver nanoparticles (Ag NPs) decorated graphene has been fabricated for the detection of various glucose concentration levels. Graphene was deposited using chemical vapour deposition technique and Ag NPs was decorated on the surface of graphene via sputtering technique. FET glucose sensor was tested under optimal conditions (pH 7.4) in linear range 0.1 mu M-0.25 mu M of glucose concentration levels. It was observed that, developed FET glucose sensor delivers high sensitivity which was compared with previously reported electrodes. The reproducibility of FET based glucose sensor was tested using different interfering species along with glucose concentrations. On examining the behavioural characteristics of FET sensor towards glucose detection it was found to offer a potential device for further real-time clinical applications. [GRAPHICS]
