In the present work, Graphene oxide (GO) was prepared using improved modified Hummer’s method. Reduced
Graphene oxide (rGO) is synthesized by cow urine extract using sonication and refluxing process. Tin Oxide quantum dots were
synthesized using wet chemical method. RGO/SnO2 based pellets were prepared using hydraulic press. These pellets were
characterized for glucose. Structural and optical characterization of GO, rGO and SnO2 quantum dots was performed using XRD,
UV-visible and FTIR. The sensors show good response towards glucose.
