    Abstract: Various embodiments of the present invention relate to plasmonic electric-field concentrators and to systems incorporating the plasmonic electric-field concentrators to perform Raman spectroscopy. In one aspect, a plasmonic electric-field concentrator comprises two or more large features, and a relatively small feature similar in shape to large features positioned adjacent to the two or more large features. The features are arranged so that when light of an appropriate wavelength is incident on the features, surface plasmon polaritons form on the outer surfaces of the features. The surface plasmon polaritons have associated electric fields extending perpendicular to the surfaces of the features. The electric fields are concentrated in the space between features forming an electric field hot spot that enhances Raman scattered light emitted from an analyte proximate to or absorbed on the features.

    Abstract: A surface enhanced Raman spectroscopy (SERS) apparatus, system and method employ a plurality of nanorods configured to vibrate. The apparatus includes the nanorods having tips at free ends opposite an end attached to a substrate. The tips are configured to adsorb an analyte and to vibrate at a vibration frequency. The apparatus further includes a vibration source configured to vibrate the free ends of the nanorods at the vibration frequency in a back-and-forth motion. Vibration of the nanorods is configured to facilitate detection of a Raman scattering signal emitted by the analyte adsorbed on the nanorod tips. The system further includes a synchronous detector configured to receive the Raman signal and to be gated cooperatively with the vibration of the nanorods. The method includes inducing a vibration of the nanorods, illuminating the vibrating tips to produce a Raman signal, and detecting the Raman signal using the detector.

    Abstract: A method of positioning a catalyst nanoparticle that facilitates nanowire growth for nanowire-based device fabrication employs a structure having a vertical sidewall formed on a substrate. The methods include forming the structure, forming a targeted region in a surface of either the structure or the substrate, and forming a catalyst nanoparticle in the targeted region using one of a variety of techniques. The techniques control the position of the catalyst nanoparticle for subsequent nanowire growth. A resonant sensor system includes a nanowire-based resonant sensor and means for accessing the nanowire. The sensor includes an electrode and a nanowire resonator. The electrode is electrically isolated from the substrate. One or more of the substrate is electrically conductive, the nanowire resonator is electrically conductive, and the sensor further comprises another electrode. The nanowire resonator responds to an environmental change by displaying a change in oscillatory behavior.
