Surface-Enhanced Raman Scattering (SERS) Performance of Metal Scale Replicas,a basic and powerful tool to study molecular configurations. This technique can obtain similar but complementary information to IR spectroscopy, especially with the rapid development of laser technology. However, Raman spectrum is not easy to acquire as the Raman scattered beam is usually weak.

These 3D subwavelength metallic structures are, however, difficult to prepare. By contrast, the 3D superstructures of butterfly win
