We have developed ultrahigh-sensitive single molecular spectroscopy by using nano-photonic devices including optical microresonators and nanofibers and have applied this method to single photosynthetic light-harvesting pigment-protein complexes. We have demonstrated (1) the single molecular observation of the light-harvesting complexes at room temperature with a conventional objective and (2) high-sensitive fluorescence detection of quantum dots using nanofiber (6.6% of the total emission photons was detected). These facts suggest that it is possible to detect fluorescence of single light-harvesting complexes with 4-times greater fluorescence collection efficiency.
