Nearly a century ago, Ernst Ruska and Max Knoll provided the first demonstration of a microscope that could image specimens using electrons rather than light. The earliest images obtained via this ...

Scanning Electron Microscopy (SEM) has revolutionized the realm of microscopic analysis. By delivering astonishingly detailed images of minuscule entities such as insects, bacteria, or even the ...

Ultrastructure expansion microscopy of murine male germ cells reveals the fine molecular structures of centrioles (shown in the enlarged image). DNA is stained in blue, and the chromosome axis in red.

Structure of the newly decoded protein found in the membrane of sperm cells. Colours mark the different units of the protein, which can be put together to make a functioning protein like the building ...

With the inventions of transmission electron microscopy (TEM) in 1931 and scanning electron microscopy (SEM) shortly after in 1937, scientists gained an unprecedented ultrastructural view of the ...

Taking images of tiny structures within cells is tricky business. One technique, cryogenic electron tomography (cryoET), shoots electrons through a frozen sample. The images formed by the electrons ...
