Abstract :
We fabricate a large area (3 × 3 cm2) polydimethylsiloxane-based substrate for surface-enhanced Raman scattering by combining femtosecond laser microstructuring and soft lithography techniques. The substrate exhibits broadband absorption in the region of 350-1000 nm and reproducible enhancement factor ~107.
