Nanotechnology enables the creation of functional materials, devices, and systems by controlling matter at the atomic and molecular scales. Precise assembly of nanoscale metal particles into optimized geometries is attractive for several applications. Despite the abundant literature on nanoparticles, their routine usage is hampered by the limited reproducible preparation of well defined, reliable and stable surfaces for large quantities routine analysis.We are actively involved in the development of highly ordered nanomaterial geometries with multi-detection modalities in large quantities. The optical properties of metallic nanoparticles, particularly gold and silver, provide a wide range of opportunities, all of which ultimately arise from the collective oscillations of conduction band electrons (�plasmons�) in response to external electromagnetic radiation. In this talk, I will bring to light advances in synthesis, characterization, and rational design assemblies of metallic and hybrid nanoparticles for chemical sensing via SERS, environmental and solar fuel applications.
