| Outline of Final Research Achievements |
Proteins associate with other proteins and form protein complexes, localizing in a specific positions in cells and tissues for their functions. The correlative light-electron microscopy (CLEM) of a sample in liquid is highly required to determine their localization at high resolution. To realize electron microscopy in solution, environmental-capsule electron microscopy (EC-EM) has been developed. However, the limited space around the sample holder of standard TEM, preclude the simultaneous observation using OM with high resolution objective lens of large NA. We have developed atmospheric scanning electron microscopy (ASEM) with inverted SEM to allow the use of an open sample container sandwiched by OM and SEM. In this research, we have tested many fluorescent substances, including GFP, qDot and ZnO. Further the markers tested here should be exploited for the application to various biological fields including basic biology, medical research, agriculture, drug discovery and diagnosis.
