Resumen:
Robust and reproducible metallized nano/microstructured surfaces of
polymeric surfaces have been successfully prepared by direct laser
interference patterning (DLIP) of commercial polymeric films followed by
sputtering of metallic thin films. The SERS spectra for 2-thioaniline
adsorbed on a structured polycarbonate surfaces covered with a gold or
platinum film showed a ca. three order of magnitude enhancement over a
flat surface with the same metal film. The method here reported is
suitable for mass production of substrates for SERS since large areas
(several cm2) can be structured in ca. 1?5 s.
