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