Abstract
Chemical sensors, devices and systems including the same, and related methods are disclosed. In an embodiment, a medical device is included having a graphene varactor including a graphene layer and a self-assembled monolayer disposed on an outer surface of the graphene layer through non-covalent interactions between the self-assembled monolayer and a π-electron system of graphene. The self-assembled monolayer includes one or more pillarenes, substituted pillarenes, calixarenes, substituted calixarenes, peralkylated cyclodextrins, substituted peralkylated cyclodextrins, pyrenes, or substituted pyrenes, or derivatives of each. Other embodiments are also included.
