    Sammanfattning : With the rapid development of nanoscience and nanotechnology, surface plasmon photonics using metal nanoparticles and nanostructures gain increasing interest, not only for fundamental scientific studies, but also for electronic, optical, and sensor applications. In the nanoscale, the physical and chemical properties of metallic particles, especially their optical properties, strongly depend on size and shape, as well as on surrounding media and structures.

  7. 10. Raman and Fluorescence Spectroscopy of Single Molecules and Metal Particles

    Författare :Jerk Bjerneld; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laser-induced; single-molecule spectroscopy; surface-enhanced Raman scattering; nanoparticles;

    Sammanfattning : Technological and conceptual advances have led to the realization of single-molecule spectroscopy. This permit detailed investigations of heterogeneous systems in fields ranging from condensed matter physics to biochemistry. It was recently discovered that surface-enhanced Raman scattering (SERS) can be used to study single molecules. LÄS MER
