1. A process for detecting a target molecule with a sensor, device comprising:
providing a sensor device comprising a channel and first and second electrodes electrically connected to the channel, wherein the channel comprises a monolayer of surface functionalized graphene or surface functionalized carbon nanotubes, wherein the surface functionalized graphene or surface functionalized carbon nanotubes comprises an imidazolidone compound, wherein the imidazolidone compound is of formula (1):wherein R1 and R2 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;
immobilizing probe molecules with the surface functionalized graphene or surface functionalized carbon nanotubes; and binding target molecules to the probe molecules.
