Metasurfaces comprised of nanosphere oligomers with uniform narrow gap spacings, their method of fabrication and applications in sensing

摘要

Nanoarchitectures comprised of subwavelength metal nanosphere oligomers with uniform narrow gap spacings for plasmonic and metamaterial devices are described, as well as methods of fabrication thereof, a biosensor system based thereon, and methods of detection of pathogenic or other organisms (e.g., bacteria) using the same.
