In order to perform such tasks, researchers have had to rely on non-optical options like electronmicroscopy.
为了实现这样的任务，研究人员已经可以依靠电子显微镜等非光学成像方法进行试验研究了。

Electronmicroscopy grants researchers and clinicians access to a universe that is too small to be detected using light-based microscopes.
电子显微镜让研究者和临床医生得以进入一个光学显微镜无法窥见的小宇宙。

Transmission electronmicroscopy creates images by shooting trillions of electrons through an object and measuring their absorption, deflection and energy loss.
