Biological Templates: High-Density Hotspots Engineered by Naturally Piled-Up Subwavelength Structures in Three-Dimensional Copper Butterfly Wing Scales for Surface-Enhanced Raman Scattering Detection (Adv. Funct. Mater. 8/2012)
Wing scales from 175 000 species of butterflies and moths provide huge numbers of textures for the development of surface-enhanced Raman scattering (SERS) substrates. On page 1578, Jiajun Gu, Di Zhang, and co-workers unveil how the sub-wavelength structures naturally arranged in depth in copper scale replicas can enhance the SERS properties. The finding helps bring sensitive and affordable SERS substrates to ordinary laboratories as consumables for trace-amount chemical detection.
