Abstract:
Ag nanoparticles were photocatalytically deposited on TiO2-coated insect wings (Ag/TiO2-coated insect wings). Wings of dragonfly, cicada and butterfly with different micro/nanostructured surfaces were investigated as substrates based on natural materials. We have investigated the surface enhanced Raman scattering (SERS) substrate properties of the six types of Ag/TiO2-coated insect wings. The size and shape of the deposited Ag nanoparticles were influenced by the surface structures of the insect wings. The SERS signal intensities of Rhodamine 6G adsorbed on the Ag/TiO2-coated insect wings with spherical-shaped Ag nanoparticles of 100-250 nm diameter and flake-shaped Ag nanoparticles were more than one order of magnitude larger than those on the Ag thin film grown by sputtering on glass slides.
