The unique optical properties of arrays of metallic nanoparticles are of great interest for a range of applications including optical data storage, sensing, optoelectronic devices or as platforms to improve on the detection limit in spectroscopic measurements. This work presents for the first time a study of nanocavities-shaped supra(meta)molecular arrangements of metamolecular units, designed and fabricated using electron beam lithography, with strong plasmonic performances. Such novel designed structures are compelling candidates for the development of highly sensitive label-free biosensors due to their unique surface plasmon resonances (SPRs) and SPR enabled Surface-Enhanced Raman Spectroscopy (SERS).
