Gap Nanoantennas toward Molecular Plasmonic Devices

Figure 13

(a–c) Gold nanoantenna not exposed to FIB milling after surface functionalization: (a) SEM image, (b) optical transmission microscopy image, and (c) fluorescence microscopy image. (d–f) Same respective images for a gold nanoantenna where the gap size had been increased by FIB milling but without exposing the lower ITO layer.
