▎ 摘　　要

NOVELTY - Detecting a target molecule with a sensor device, involves: providing a sensor device comprising a channel and first and second electrodes electrically connected to the channel, where the channel comprises a monolayer of surface functionalized graphene or surface functionalized carbon nanotubes, and the surface functionalized graphene or surface functionalized carbon nanotubes comprise(s) an imidazolidone compound; immobilizing probe molecules with the surface functionalized graphene or surface functionalized carbon nanotubes; and binding target molecules to the probe molecules. USE - The process is useful for detecting a target molecule, preferably streptavidin, with a sensor device, preferably a FET biosensor (all claimed). ADVANTAGE - The method provides a real-time detection of the target molecule in a rapid manner.
