Abstract: A system and method suitable for selection, manipulation, and analysis of individual particles within a fluid medium. The system and method involve manipulating the particles by contacting the fluid medium with a plasmonic nanoantenna, illuminating the plasmonic nanoantenna with a source of light such that the plasmonic nanoantenna acts as a nanoscale heat source resulting in localized heating of the fluid medium creating local gradients in the electrical properties of the fluid medium that yield plasmonic trapping sites in the vicinity of the plasmonic nanoantenna, and applying an alternating current electric field in the fluid medium to create electrothermoplasmonic flow around the plasmonic nanoantenna. The electrothermoplasmonic flow transports at least one of the particles towards the plasmonic nanoantenna and the particle is trapped by at least one of the plasmonic trapping sites.

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.

Abstract: A method of making an optical device including forming a plurality of holes with varying radii milled vertically into a film, wherein said holes form a pattern. The radius of each hole determines an effective refractive index for said hole. The effective refractive index modifies a phase and an intensity of an incoming electromagnetic radiation as the radiation propagates through said hole. The device is configured to be operating equally for each linearly polarized radiation simultaneously, wherein the each linearly polarized radiation is normally incident on the device.

Abstract: A planar optical device, comprised of sets of nanometer-scale holes milled into a thin metal or ceramic film of subwavelength thickness serves to form arbitrary waveform of light. The holes form a pattern, preferrably rings, of various sizes in order to achieve a given phase front of light due to photonic effect. When designed as a lens, the device focuses incident light into a tight focal spot. In symmetric design, the focusing property of the device does not depend on the incident polarization angle. The lens can be manufactured based on high-throughput fabrication methods and easily integrated with a chip or placed at the end of an optical fiber.

Abstract: Titanium nitride (TiN) nanofurnaces are fabricated in a method that involves anodization of a titanium (Ti) foil to form TiO2 nanocavities. After anodization, the TiO2 nanocavities are converted to TiN at 600° C. under ammonia flow. The resulting structure is an array of refractory (high-temperature stable) subwavelength TiN cylindrical cavities that operate as plasmonic nanofurnaces capable of reaching temperatures above 600° C. under moderate concentrated solar irradiation. The nanofurnaces show near-unity solar absorption in the visible and near infrared spectral ranges and a maximum thermoplasmonic solar-to-heat conversion efficiency of 68 percent.
