Nanoparticle-decorated nanocanal arrays show significant enhancement of Raman scattering for a model explosive-related dinitrotoluene compound. The Raman scattering by gold nanoparticles distributed along nanocanals (see image) is efficiently combined with optical-wave guiding to allow significant surface-enhanced Raman scattering.
