Using a dynamic oblique-angle deposition technique, we have demonstrated the direct formation of Ag nanorods with quasiparallel major axes on a template layer of oxide having a strongly anisotropic surface morphology. The optical properties of the nanorods are tuned by the deposition conditions without any pre- or post-treatment, and the resulting nanocoatings containing the Ag nanorods exhibit high surface-enhanced Raman scattering (SERS) activity. In addition to high uniformity over a large area, our nanocoatings contain a large number of isolated nanorods with a high density. Using the optimum Ag nanorods, SERS imaging of microdroplets of a rhodamine 6G solution has been successfully demonstrated. The space resolution of the imaging is of the order of at least a few μm. These features are quite appropriate for the SERS imaging of biomaterials.
