| Research Abstract |
Aims of this research project are development and application of novel imaging method that can informs molecular morphology and function of biological specimens. In the present research, we have focused on the second harmonic generation (SHG) microscopy and cathode luminescence(CL) microscopy.A polarization resolved, high-speed SHG microscope was developed. In in vivo measurement with this microscope, age related dermis collagen image were observed. Also we demonstrated SHG imaging of tissue-engineered cartilage composed of rabbit chondrocytes and type I collagen gel. From this, we confirmed that it is suitable for evaluating the quality of tissue-engineered cartilage. In the CL microscopy, three kinds of rare-earth-doped nanophosphors were synthesized and injected into macrophages. The spatial distribution of nanophosphors was visualized by using a scanning electron microscope CL system.
