    摘要: An electrically driven device (10) for surface enhanced Raman spectroscopy includes a first electrode (16), a substrate (12) positioned proximate to the first electrode (16), a plurality of cone shaped protrusions (12′) formed integrally with or on a substrate surface (S), a Raman signal-enhancing material (14) coated on each protrusion (12′), and a second electrode (18) positioned relative to the first electrode (16) at a predetermined distance, D. Each of the protrusions (12′) has a tip (22) with a radius of curvature, r, ranging from about 0.1 nm to about 100 nm. The second electrode (18) is positioned relative to the first electrode (16) such that the electrodes (16, 18) together produce an electric field (EF) when a voltage bias is applied therebetween. The electric field (EF) has a field distribution that creates a stronger field gradient at a region proximate to the tips (22) than at other portions of the substrate (12).

    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.
