Cryogenic-electron microscopy (cryo-EM) has rapidly become one of the most important experimental methods in structural biology and nanoscience. In this article, AZoNano discusses the working ...

Image Credit: Laser Quantum Ltd A Brief Introduction to SEM and TEM It is important to discuss the main working principles of EM before outlining the principles of time-resolved electron microscopy.

Detection of either kind of electron allows for reconstruction of the size of the imaged object as well as visualization of any more complex structural features. Cryo-electron microscopy (cryo-EM) ...
