Spectral analysis of surfaces at subwavelength resolution

polymeric surfaces, Langmuir-Blodget films and biological samples can be investigated in-situ, in air orwater, and without radiation or otherwise induced damage. Luminescent or Raman active surface sites ormolecules can be detected, in principle, with atomic or molecular resolution and, furthermore, characterizedvia single site luminescence or Raman spectra. The goal of this research is a fluorescence nanoscope thatwill have the capability to zoom-in non-destructively, in water, air or vacuum, from the limits of resolution of
