我们开发了一种高分辨率的荧光显微镜,其中荧光材料直接激发使用聚焦电子束。电子束激发使纳米尺度上的详细观察成为可能。使用薄膜将研究环境与电子束传播所需的真空区域分开,也可以进行实时活细胞观察。在这项研究中,我们展示了观察细胞成分的自发荧光激发的聚焦电子束和进行动态观察细胞内颗粒。由于自发荧光与细胞中的内源性物质有关,因此该显微镜也可用于研究细胞器的内在性质。
We developed a high-resolution fluorescence microscope in which fluorescent materials are directly excited using a focused electron beam. Electron beam excitation enables detailed observations on the nanometer scale. Real-time live-cell observation is also possible using a thin film to separate the environment under study from the vacuum region required for electron beam propagation. In this study, we demonstrated observation of cellular components by autofluorescence excited with a focused electron beam and performed dynamic observations of intracellular granules. Since autofluorescence is associated with endogenous substances in cells, this microscope can also be used to investigate the intrinsic properties of organelles.
