    Abstract: Raman-enhancing structures include a photonic crystal having a resonant cavity and at least one waveguide coupled to the resonant cavity. A nanostructure comprising a Raman-enhancing material is disposed proximate the resonant cavity of the photonic crystal. Raman-enhancing structures include a microdisk resonator, at least one waveguide coupled to the microdisk resonator, and a nanostructure comprising a Raman-enhancing material disposed proximate the microdisk resonator. Methods for performing Raman spectroscopy include generating radiation, guiding the radiation through a waveguide to a resonant cavity in a photonic crystal or a microdisk resonator, resonating the radiation in the resonant cavity or microdisk resonator, providing an analyte proximate the resonant cavity or microdisk resonator, subjecting the analyte to the resonating radiation, and detecting Raman scattered radiation.

    Abstract: An apparatus for sensing at least one property of a fluid is described. A first photonic crystal structure and a second photonic crystal structure are defined in a dielectric slab. The first and second photonic crystal structures comprise differently patterned arrays of channels extending through the dielectric slab. The apparatus further comprises a fluid introduction device configured to introduce a common volume of the fluid into the channels of the first and second photonic crystal structures. The at least one property of the fluid can be sensed by measuring the propagation of radiation through the first and second photonic crystal structures.

    Abstract: An optical sensor is provided, comprising (a) a silicon nanowire of finite length having an electrical contact pad at each end thereof; and (b) a plurality of self-assembled molecules on a surface of the silicon nanowire, the molecules serving to modulate electrical conductivity of the silicon nanowire by either a reversible change in dipole moment of the molecules or by a reversible molecule-assisted electron/energy transfer from the molecules onto the silicon nanowire. Further, a method of making the optical sensor is provided. The concept of molecular self-assembly is applied in attaching functional molecules onto silicon nanowire surfaces, and the requirement of molecule modification (hydroxy group in molecules) is minimal from the point view of synthetic difficulty and compatibility. Self-assembly will produce well-ordered ultra-thin films with strong chemical bonding on a surface that cannot be easily achieved by other conventional methods.

    Abstract: A surface enhanced Raman spectroscopy (SERS) sensor, system and method employ nanorods and independent nanoparticles that interact. The sensor includes at least two spaced apart nanorods attached at first ends to a substrate and an independent nanoparticle. Second ends of the nanorods are movable into close proximity to one another and include a Raman active surface. The nanoparticle has a functionalized surface that includes a Raman signal generator. An interaction between the nanoparticle and the nanorod second ends in close proximity is detectable. The system includes the SERS sensor, an illumination source and a Raman signal detector. The method includes illuminating the interaction of the nanoparticle and the nanorods with an analyte, and detecting an effect on a Raman signal caused by the analyte.
