Nanoprisms guide and funnel light towards the metal-dielectric interface where the dielectric acts as the medium under test. The system works under normal incidence conditions and is spectrally interrogated. The performance is better than the classical Kretschmann configurations, and the values of sensitivity and figure of merit are competitive with other plasmonic sensor technologies. The geometry and the choice of materials have been made taking into account applicable fabrication constraints.engAtribución 3.0 Españajournal articlehttp://dx.doi.org/10.1186https://link.springer.com/article/10.1186/s11671-017-2347-7open access533.9535537.531Optical sensorNano-prismGuiding lightPlasmonic sensorBiosensorFísica (Física)Óptica (Física)22 Física2209.19 Óptica Física
