Biomarkers Detection on Hydrogenated Graphene Surfaces: Towards Applications of Graphane in Biosensing

Graphane, the hydrogenated form of graphene, is a material of significant interest. Here we compare properties of hydrogenated graphene and ordinary graphene used for electrochemical oxidation of important biomarkers, such as ascorbic acid, dopamine and uric acid.

Graphene for impedimetric biosensing

Graphene displays promising features for biosensing applications. Electrochemical impedance spectroscopy (EIS) is a very sensitive, label-free technique that is ideally suited to be coupled with a graphene platform. We discuss recent advances of graphene-based platforms for impedimetric genosensors and immunosensors. We also provide an overview on EIS and the preparation of graphene by different methods, …
