Mid-infrared plasmonic biosensing with graphene
Daniel Rodrigo,Odeta Limaj,Davide Janner,Dordaneh Etezadi,F. Javier García de Abajo,Valerio Pruneri,Hatice Altug +6 more
TL;DR: In this paper, the plasmon resonance of nanostructured graphene was dynamically tuned to selectively probe the protein at different frequencies and extract its complex refractive index, and the extreme spatial light confinement in graphene produced an unprecedented high overlap with nanometric biomolecules, enabling superior sensitivity in the detection of their refractive indices and vibrational fingerprints.
