| Outline of Final Research Achievements |
This project aimed to developing and demonstrating an endoscopic fluorescence correlation spectroscopy (ES-FCS), which enables to measure bio-molecular dynamics in situ. In order to realize this purpose, we constructed and improved ES-FCS. Finally, I was succeeded in the dynamics measurement of the fluorescent beads with the diameter of larger than 63 nm. The shape of measurement volume was an ellipsoid with the short radius of 1.0 micro meter and the long radius of 7.1 micro meter. This volume is smaller than cultured cells, therefore, a possibility of the molecular dynamics measurement in living cell was successfully shown.
It will be expected that the pharmacodynamics can be studied by ES-FCS measurements in live animals and plants. The ES-FCS will contribute to the development of biology and medical science.
