Highly reproducible metallized nano/microstructured polymeric surfaces have been successfully prepared by direct laser interference patterning followed by sputtering of metallic films. The SERS spectra show that a ca. three order of magnitude enhancement can be achieved. The method here reported is suitable for mass production of substrates for SERS since large areas (several cm2) can be structured in short times (≈1–5 s).
