Cryo-electron microscopy has exposed the structure of a bacterial virus with unprecedented detail. This is the first structure of a virus able to infect Staphylococcus epidermidis, and high-resolution ...

Transmission Electron Microscopes can be used for a variety of different techniques, which set them apart from other forms of microscope. The first is metal shadowing or negative staining. TEM ...

CeB 6 and tungsten are both thermionic sources with a filament referred to as a cathode, from which electrons are generated. The emission begins when the electrons are supplied with sufficient energy ...

Electron microscopy has become a vital tool in structural biology, enabling researchers to visualize biological macromolecules at near-atomic resolution. Recent advances have transformed it from a low ...
