Graphene Nanosensor for NO Metabolites Detection

Abstract

In the present study, we present the design, manufacture and analytical performance of a graphene sensor (SLG/SiO2/Si) for the in situ detection of HNO3 as a substitute measure of NO in aqueous conditions. Our electrochemical and FET studies demonstrate that the CVD graphene, which is applied as a sensing platform, can respond rapidly to NO metabolites in physiological environments with a micromolar sensitivity. These results are promising in the development of a sensor that allows real-time monitoring of the physiological levels of NO in cultured cells and plasma.
