| Research Abstract |
In this work, bidirectional electron transfer in photosynthetic photosystem I proteins was experimentally observed by using high time-resolved ESR and chemically reduced proteins. In this work, moreover, to realize highly sensitive ESR measurements applicable to a single protein, microsamples applicable to high-frequency ESR were prepared. Using an artificial electron-transfer system as a model compound, we established the procedure for preparing microsamples applicable to a tiny cavity for high-frequency ESR.
