Abstract:
1. A Raman signal-enhancing structure comprising: a first layer of Raman signal-enhancing material; a substantially monomolecular layer of molecules disposed on at least a portion of the first layer of Raman signal-enhancing material; a second layer of Raman signal-enhancing material disposed on at least a portion of the substantially monomolecular layer of molecules, the second layer of Raman signal-enhancing material being disposed on a side of the layer of molecules opposite the first layer of Raman signal-enhancing material; and a substrate, the first layer of Raman signal-enhancing material being disposed on a surface of the substrate and comprising a plurality of substantially planar islands, each island comprising a Raman signal-enhancing material.
