| Outline of Final Research Achievements |
The photosynthetic organisms in plants, algae and bacteria are nano-bio integrated photonic devices with the most efficient energy conversion function in the earth. Single molecule spectroscopic measurements on such biomolecules are an urgent task to clarify their essential electron and energy transport phenomenon. In this project, we have developed a spectroscopic system with picosecond time resolution capable of single photon level detection and real - time observation of photosynthetic energy transfer process. We also established a method to prepare a phycobilisome supercomplex with sufficient size to realize single supramolecular spectroscopy from cyanobacteria and red algae, and clarified details of their energy transfer processes.
