Chemical varactor based sensor with non covalent surface modification of graphene

摘要

Medical devices that can include graphene varactors (100).Graphene varactor (100) is a graphene layer π－π A self-organized monolayer disposed on the outer surface of the graphene layer through the stacking interaction can be included.The self-assembled monolayer may provide at least 0.9 Langmuir theta values.Self assembled monolayers can include polycyclic aromatic hydrocarbons, Tetraphenylporphyrins or their derivatives, metal Tetraphenylporphyrins or aromatic cyclodextrins.A corresponding manufacturing method and methods for detecting analytes in a patient's gaseous sample using this medical device are also disclosed.
