The scope of biological research has been severely restrained by the absence of the ultrasensitive, chemically-selective and sub-diffraction-limit-resolving optical microscope. To date, the stimulated emission depletion (STED) microscopy has been the strongest candidate to resolve the desire for a “perfect” microscope; however, it still relies on the tagging of the fluorescent particles to the analytes. Thus, scientists intend to develop a far field nano-optical imaging method without requiring any staining. To get this end, we first seek an optical modality which extracts intrinsic chemical/materials specific contrasts from the objects; the coherent Raman microscopy has offered the closest solution to this challenge. The diverse features of this talk concerning Raman-based spectro/microscopy will include the introduction of the new concepts, several technical development and critical upcoming prospects.
