High reproducible surface-enhanced Raman scattering (SERS) substrates with the hexagonal arrays of nanopores or nanoconcaves are fabricated by anodization of aluminum and silver sputtering. Each substrate exhibits a strong and reproducible SERS signal of a probing molecule, while its variation across the chosen area is revealed by the Raman imaging technique.
