Research Abstract |
Optical imaging technique with a fluorescent label is a common tool to understand the mechanism of pathogenesis and the vital functions in cellular and molecular level. In this study, We developed a hollow fiber bundle as a basic technique for medical application of the optical imaging that combined deep tissue imaging with nonliner optics such as two-photon excited fluorescence and second harmonic generation (SHG) and endoscopic technique. In the result, the fiber coupling system was constructed and evaluated in biological samples. Two-photon fluorescence images and SHG images of the tissues in mice were successfully obtained using the hollow fiber bundle. These results suggest that the hollow fiber bundle technique is a promising as a practical tool for endoscopic application in the future.
