| Outline of Final Research Achievements |
Recently, microscopic imaging techniques with high intensity lasers such as single molecule imaging and super resolution imaging have attracted attention. However, one of the unsolved problems is photobleaching of fluorophores under the microscopic measurement. In this project, we developed new technologies to suppress photobleaching of fluorescent dyes.
In the first year, we investigated whether photobleaching can be suppressed by incorporating a fluorescent dye in a host molecule. The photobleaching was dramatically inhibited by an appropriate combination of a certain type of dye and host. In the second year, we discovered the anti-fading effect of some lanthanide ions. We also considered the anti-fading mechanism.
