Nanoscopy and nanospectroscopy This book builds a narrative on the near field optical and spectroscopic studies with an emphasis on plasmonic and photonic assisted nano optics as a tool for super lensing. Deliberations on near field studies using confined light in various applications are included along with their commercial implications. Single molecule detection utilizing efficient surface enhanced Raman scattering phenomenon in the far field and plasmonic tip enhanced Raman scattering studies in the near field measurements for fast analysis upto trace level is discussed. Features: Covers the broad area of nano optical spectroscopy from the perspective of putting the concepts and innovations in the field to use. Discusses entire spectra of near field optics and spectroscopy using light. Includes dielectric nanophotonics and optical confinement. Studies acoustic phonon confinement for analysis of chemical biological and other materials. Explores gas chemical sensing using surface plasmon resonance (SPR) in the Kretschmann configuration. This book is aimed at graduate students and researchers in material science analytical chemistry nanotechnology and electrical engineering Theory of light scattering and applications T.R.
