| Outline of Final Research Achievements |
The aim of this research was development of a new fluorescent endoscopic surgical system and we had the study results as below.
1.We created an original organic fluorescent probe and analyzed the property of this particle. This probe had advantages in fluorescent signal intensity and degradation time compared with quantum dot or ICG.2.We developed an original gastrointestinal endoscopic clip with the new fluorescent probe. 3.We developed an original fluorescent endoscopic surgical system and refined the conditions for human application in the future.4.We successfully detected the fluorescent signal of the clips from outside of the gastrointestinal tract in pig model using our original surgical system.5.We performed analysis of the fluorescent property and dynamics of the original fluorescent particle in living tissues.
