Abstract: An optical sensor system, comprising refractory plasmonic elements that can withstand temperatures exceeding 2500° C. in chemically aggressive and harsh environments that impose stress, strain and vibrations. A plasmonic metamaterial or metasurface, engineered to have a specific spectral and angular response, exhibits optical reflection characteristics that are altered by varying physical environmental conditions including but not limited to temperature, surface chemistry or elastic stress, strain and other types of mechanical load. The metamaterial or metasurface comprises a set of ultra-thin structured layers with a total thickness of less than tens of microns that can be deployed onto surfaces of devices operating in harsh environmental conditions. The top interface of the metamaterial or metasurface is illuminated with a light source, either through free space or via an optical fiber, and the reflected signal is detected employing remote detectors.

Abstract: Disclosed herein are nanoparticle-based plasmonic solutions to therapeutic applications employing titanium nitride (TiN) and other non-stoichiometric compounds as the plasmonic material. Current solutions are suboptimal because they require complex shapes, large particle sizes, and a narrow range of sizes, in order to achieve plasmonic resonances in the biological window. The nanoparticles discloses herein provide plasmonic resonances occurring in the biological window even with small sizes, simple shapes, and better size dispersion restrictions. Local heating efficiencies of such nanoparticles outperform currently used Au and transition metal nanoparticles. The use of smaller particles with simpler shapes and better heating efficiencies allows better diffusion properties into tumor regions, larger penetration depth of light into the biological tissue, and the ability to use excitation light of less power.
