Nano-Structure Physiology

Kazuyoshi Murata(Assos. Prof.)


Our research goal is to reveal the relationship between biological functions and structures. For this purpose, we use different types of state-of-the-art electron microscopes (Figure). First, the Zernike phase-plate electron cryomicropscope with energy filter (JEM-2200FS: 200kV) is used for high-resolution structural analyses of non-stained biological samples. Second, the high voltage electron microscope (HVEM) for biologcal research (H-1250M: 1MV) equipped with a direct detection CMOS camera is employed to visualize the three-dimensional structures of thick biological specimens, like cell and neuron. The serial block-fase SEM is also used for the further thick materials, like tissues and neural circuits. By using these microscopes, we carry out a structural biology from molecules to cells.
