摘要： Embodiments of the present invention are directed to nanowire-based systems for performing surface-enhanced Raman spectroscopy. In one embodiment, a system comprises a substrate (102) having a surface and a plurality of tapered nanowires (104) disposed on the surface. Each nanowire has a tapered end directed away from the surface. The system also includes a plurality of nanoparticles (110) disposed near the tapered end of each nanowire. When each nanowire is illuminated with light of a pump wavelength, Raman excitation light is emitted from the tapered end of the nanowire to interact with the nanoparticles and produce enhanced Raman scattered light from molecules located in close proximity to the nanoparticles.

摘要： A sensing device that produces a Raman signal includes micro-rods or nano-rods arranged on a substrate in a two-dimensional (2D) array, each of the rods having a length in a single row being substantially the same, with the rod length of each row being different from the rod length of each other row. Each row of rods has a respective resonant vibration frequency that varies from row to row. A source of vibration energy, operatively connected to the substrate, excites vibration in each of the rods such that a responding row resonates when an exciting frequency approaches the resonant vibration frequency of the responding row. A method includes exposing the 2D array to a light source and analyzing Raman scattering at each rod of the 2D array to render a Raman map.

摘要： Raman spectroscopy systems include an analyte, a radiation source configured to emit incident radiation having a wavelength, and a detector that is capable of detecting only radiation having wavelengths within a detectable range that includes at least one wavelength corresponding to hyper Raman scattered radiation scattered by the analyte. The wavelength of the incident radiation is outside the detectable range. In particular systems, all wavelengths of radiation that are scattered in the direction of the detector impinge on the detector. Raman spectroscopy methods include providing an analyte and irradiating the analyte with incident radiation having a wavelength, providing a detector capable of detecting only wavelengths of radiation within a detectable range that does not include the wavelength of the incident radiation, and detecting Raman scattered radiation scattered by the analyte. A continuous path free of radiation filters may be provided between the analyte and the detector.
