Shiny silver: A superstructure consisting of Ag nanoparticles and CdTe nanowires connected by a streptavidin (SA) and D-biotin (B) affinity pair displays twofold enhancement of the nanowire luminescence. The optical process involved could also be operative in other metamaterials and could serve as a basis for applications in a variety of optoelectronic devices.
