Abstract Scope |
Noble metal nanoparticles, particularly gold and silver, have exciting physical and chemical properties that are entirely different from the bulk. For chemical sensing and imaging, the optical properties of metallic nanoparticles 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. The optical properties of the anisotropic and isotropic nanomaterials become very important for examining surface-enhanced Raman scattering (SERS) effects. SERS can be used for detection of traces amount of substances for a large variety of molecules of environmental, biomedical, and pharmaceutical of interest. In this talk, I will describe recent advances in chemical analyte detection and optical imaging applications using anisotropic metallic nanoparticles. |
