摘要
Provided are patterned nanoporous gold (“P-NPG”) films that may act as at least one of an effective and stable surface-enhanced Raman scattering (“SERS”) substrate. Methods of fabricating the P-NPG films using a low-cost stamping technique are also provided. The P-NPG films may provide uniform SERS signal intensity and SERS signal intensity enhancement by a factor of at least about 1×107 relative to the SERS signal intensity from a non-enhancing surface.
