dc.description.abstractGraphene oxide (GO) has been synthesized through simple experimental method and used for surface modification of glassy carbon electrode, thus developed a new efficient GO/GCE as a sensor for identification and quantification of Caffeine in beverage samples. Common analytical techniques have been employed to establish the physiochemical properties of graphene oxide. The electro catalytic activity GO/GCE has been examined towards sensing and quantification of caffeine through Cyclic voltammetry and Differential pulse voltammetry. The results show high sensitivity with a wide linear range in concentration 3.2-183 µM and low detection limit (LOD) 0.043 µM. In addition, in order to inspect the real time application of GO/GCE, it has been also employed to determine the concentration of caffeine in cola, Red bull and coffee samples.Very low LOD has been observed for caffeine even in real sample analysis and hence this electrode can very well be expended for real time application and thus enable to maintain the quality control of the food samples.en_US
