In article number 2005814, Jiang Li, Huabin Wang, and co‐workers demonstrate the imaging of single protein molecules with a scattering‐type terahertz (THz) scanning near‐field optical microscope, taking advantage of a graphene substrate with high THz reflectivity and atomic smoothness, and a long platinum probe with high scattering ability. This strategy opens new routes to imaging single biomolecules with THz techniques.
