Electroactivity of graphene oxide on different substrates
Graphene oxide is known to be electroactive on carbon materials due to the reduction of various inherent oxygen functionalities on its surface. In this work, we show that the characteristic reduction peak of graphene oxide ...
Electrochemistry of folded graphene edges
There is enormous interest in the investigation of electron transfer rates at the edges of graphene due to possible energy storage and sensing applications. While electrochemistry at the edges and the basal plane of graphene ...
Large-scale quantification of CVD graphene surface coverage
The extraordinary properties demonstrated for graphene and graphene-related materials can be fully exploited when a large-scale fabrication procedure is made available. Chemical vapor deposition (CVD) of graphene on Cu ...
Impedimetric immunoglobulin G immunosensor based on chemically modified graphenes
Immunosensors which display high sensitivity and selectivity are of utmost importance to the biomedical field. Graphene is a material which has immense potential for the fabrication of immunosensors. For the first time, ...
Thrombin aptasensing with inherently electroactive graphene oxide nanoplatelets as labels
Graphene and its associated materials are commonly used as the transducing platform in biosensing. We propose a different approach for the application of graphene in biosensing. Here, we utilized graphene oxide nanoplatelets ...
