Within cells lies an intricate, microscopic world that remains invisible to the human eye. To visualize cellular details, scientists rely on the power of electron microscopes. With unparalleled ...

Traditional electron microscopy techniques include scanning electron microscopy (SEM) and transmission electron microscopy (TEM), where electrons that interact with the sample are imaged. 4 The ...

Electron microscopy is a powerful technique that provides high-resolution images by focusing a beam of electrons to reveal fine structural details in biological and material specimens. 2 Because ...

Since the development of the transmission electron microscope (TEM) in the 1930s, imaging biological samples in their aqueous environment has been a main challenge 1,2. This difficulty arises because ...
