Disclosed herein is a plasmonics platform comprising a substrate; a plurality of periodically spaced nanoholes and/or nanoparticles disposed upon the substrate; wherein the average first order of periodicity between the nanoholes and/or the nanoparticles is about 5 to about 1,000 nm; and a microelectromechanical and/or a nanoelectromechanical system in operative communication with the substrate so as to vary the average first order of periodicity between the nanoholes and/or the nanoparticles.

Embodiments of the invention include a system for sensing homonuclear diatomic molecules, such as, for example, nitrogen. Other embodiments include a method for sensing homonuclear diatomic molecules. The system may include a light source, a hollow-core wave-guiding device that exhibits a low attenuation at predetermined operating optical frequencies and is in optical communication with the light source, a gas introduction system for introducing a gaseous medium between the light source and the hollow-core wave-guiding device, and a detector in optical communication with the hollow-core wave-guiding device.

Hollow-core waveguide-based raman systems and methods

The provision of an ionic self-assembled multilayer (ISAM) film on a fiber-optic element including a long period grating (LPG) by a simple, room temperature process provides tuning of the LPG and/or high sensitivity to the refractive index of the ambient environment of the fiber-optic element. Inclusion of a final layer or a probe, receptor or affinity ligand in the multi-layer film provides a highly sensitive sensor for specific chemical and biological materials. Use of a turn around point (TAP) LPG allows detection to be performed by detection of light intensity rather than wavelength of attenuation. Use of a material having an electro-optical response to an electrical field by change of dimension or refractive index allows the combination of a LPG or TAP LPG and ISAM film to function as a light modulator.
