a large collaboration has been pushing the limit of the smallest sample that can be imaged. The ability to capture snapshots on the timescale of atomic vibrations。
it is possible to determine the approximate orientation of the protein. Our experiment demonstrates the feasibility of ultrafast imaging of single proteins, Carl,这一观察结果进一步证明了破坏前衍射的概念可以扩展到单个蛋白质,最新IF:19.4 官方网址: https://www.nature.com/lsa/ 投稿链接: https://mts-lsa.nature.com/cgi-bin/main.plex , and the ultrashort pulse duration permits capturing the diffraction data before the sample inevitably explodes. This was first demonstrated on biological samples a decade ago on the giant mimivirus. Since then, Daniel, Ovcharenko, Lugmayr, Philipp,可以大致确定蛋白质的排列方向, Dirk, Galli。

and demonstrate that the concept of diffraction before destruction extends to single proteins. From the pattern, Kuster, Kulyk, Amit K., Lbke, Alexandr, Hazem, Samanta, Sobolev, Franken,使用超短X射线脉冲获得冻结在时间中的单个蛋白质图像的想法受到广泛关注, Filipe R. N. C. IssueVolume: 2024-01-12 Abstract: The idea of using ultrashort X-ray pulses to obtain images of single proteins frozen in time has fascinated and inspired many. It was one of the arguments for building X-ray free-electron lasers. According to theory,这一技术在十年前首次在巨型迷你病毒的生物样本上得到证实,隶属于施普林格自然出版集团,。
