Abstract:
1. A process of manufacturing a sensor device, the process comprising: overlaying a dielectric layer onto a substrate; depositing graphene or carbon nanotubes onto the dielectric layer; forming a source electrode and a drain electrode on the substrate such that the graphene or carbon nonotubes layer defines a channel therebetween and is electrically connected to the source and drain electrodes; and functionalizing a surface of the graphene or carbon nanotubes with an imidazolidone compound, wherein the imidazolidone compound is of formula (1): wherein R 1 and R 2 are each independently selected from the group consisting of hydrogen, an alkyl group with 1 to 16 carbon atoms, an amine group, an alkylamine group, an aldehyde group and a carboxylic acid and an ester.
