Tunable resonant surface plasmons (SPs) based on graphene nanoribbon are studied to detect nanoscale protein molecules in mid-infrared (mid-IR) region. The two-dimensional nature of the collective oscillations of Dirac quasi-particles result in a strong electric field confinement of graphene plasmon...
