- •
Al alloy as a solid support of concave gold nanocubes as an efficient SERS substrate.
- •
Concave gold nanocubes act as efficient nanoantennas.
- •
Aluminum alloys does not exhibit fluorescence or Raman signal such as glass, paper or plastic.
- •
Nanometric roughness of Al alloy was controlled by means of electropolishing procedure.
- •
Hydrothermal treatment of Al allows the formation of pseudoboehmite (γ-AlO(OH).
