Facilitating surface enhanced Raman spectroscopy

摘要

An apparatus and related methods for facilitating surface-enhanced Raman spectroscopy (SERS) are described along with methods for fabricating the apparatus. For one embodiment, the apparatus comprises a metallic fishnet defining a plurality of voids therein. The metallic fishnet exhibits at least one acute V-shaped cross-sectional feature between at least one adjacent pair of the voids.
