Nanoplasmonics: The Physics behind the Applications - Mark I. Stockman
From Katie Gentilello
Nanoplasmonics deals with collective electron dynamics on the surfaces of metal nanostructures, which arises due to excitations called surface plasmons. The surface plasmons localize and concentrate optical energy in nanoscopic regions creating highly enhanced local optical fields. Nanoplasmonic fields are also ultrafast: changing on the femtosecond or even attosecond scale. Fundamentals of surface plasmonics will be discussed. The properties of the surface plasmons and their local fields are in the foundation of the numerous applications of nanoplasmonics to science, technology, environmental monitoring, biomedicine, and defense. A brief review of some of these applications will be given. We will discuss in more detail some of these applications: biomedical diagnostics including detection of pathogenic viruses, cancer theranostics, single molecule spectroscopy, and detection of explosives using the spaser (surface plasmon amplification by stimulated emission of radiation).
