Abstract
A surface-enhanced Raman spectroscopy device includes a substrate, and an ultraviolet cured resist disposed on the substrate. The ultraviolet cured resist has a pattern of cone-shaped protrusions, where each cone-shaped protrusion has a tip with a radius of curvature equal to or less than 10 nm. The ultraviolet cured resist is formed of a predetermined ratio of a photoinitiator, a cross-linking agent, and a siloxane based backbone chain. A Raman signal-enhancing material is disposed on each of the cone-shaped protrusions.
