Surface-enhanced Raman spectroscopy (SERS) substrates are prepared by electroless Ag metallization and vapor phase Au deposition on nanostructured poly(chloro-p-xylylene) (nanoPPX) templates. These substrates exhibit quasi-periodic nanomorphology inherited from the underlying nanoPPX template, resulting in highly reproducible SERS signal (
