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 superlensing. 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 up to trace level is discussed.


  • 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
  • Explores gas/chemical sensing using surface plasmon resonance (SPR) in the Kretschmann configuration
  • Includes dielectric nano-photonics and optical confinement
  • Studies phonon behaviour using confined light for the analysis of chemical, biological, and other materials

This book is aimed at graduate students and researchers in material science, analytical chemistry, nanotechnology, and electrical engineering.
