Development of environmental cell with graphene thin film for scanning electron microscope.

我们的目标是利用石墨烯薄膜开发环境电池。该环境池用于扫描电子显微镜，并适用于单分子观察方法之一的绕射电子传输(DET)。DET可以应用于生理条件下的生物分子，并将被用于药物开发和许多其他科学领域。在本项目中，我们建立了刻蚀分离石墨烯薄膜的技术，并安装了环境电池的窗口。这些技术是薄膜处理完好无损的进步。我们成功地进行了DET的研究，并在单分子水平上观察到了嗜热古菌伴侣蛋白的旋转运动。

We aimed to develop the environmental cell using graphene thin film. The environmental cell is for use in a scanning electron microscope and adapted for the diffracted electron trafficking (DET), one of the single molecular observing methods. DET can apply for biological molecule in physiological condition, and it will be used for drug development and a lot of other scientific fields. In this project, we established the techniques of isolation of the graphene thin film by etching and attached the window of the environmental cell. These techniques are a progress of treating thin film with intact. We succeeded to advance of DET and observed rotated motion of chaperonin protein from thermophilic archaea with single molecular level.
