STEM operates by focusing a beam of electrons into a narrow probe that is scanned across a thin specimen. As the electrons interact with the sample, they are either scattered or transmitted. The ...

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 ...

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 ...

(a) A scanning electron microscope (SEM) image of the nanoneedle probe used for the measurements. (b) Elasticity map of a 1 µm × 1 µm area on the nuclear surface, showing the change in elasticity ...

Researchers have combined two microscopic imaging techniques in one microscope, providing scientists with a high-resolution method of tracking single molecules in a cellular context. The development ...
