摘要： Embodiments of the present invention are directed to systems for performing surface-enhanced Raman spectroscopy. In one embodiment, a system (100, 400, 600, 800, 900, 950) for performing Raman spectroscopy comprises a substrate (102) substantially transparent to a range of wavelengths of electromagnetic radiation and a plurality of nanowires (104, 602) disposed on a surface of the substrate. The nanowires are substantially transparent to the range of wavelengths of electromagnetic radiation. The system includes a material disposed on each of the nanowires. The electromagnetic radiation is transmitted within the substrate, into the nanowires, and emitted from the ends of the nanowires to produce enhanced Raman scattered light from molecules located on or in proximity to the material.

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 having a surface and a plurality of tapered nanowires disposed on the surface. Each nanowire has a tapered end directed away from the surface. The system also includes a plurality of nanoparticles 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.
