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 ...

TEM works by accelerating electrons, typically with energies between 80 and 300 kV, and directing them through a specimen thin enough for electron transmission. Because of their very short wavelength ...

Nearly 100 years ago, a seemingly simple discovery revolutionized the microscope. The introduction of phase contrast, which ...

Using a tiny, spherical glass lens sandwiched between two brass plates, the 17th-century Dutch microscopist Antonie van Leeuwenhoek was the first to officially describe red blood cells and sperm cells ...

Cryo-electron microscopy (cryo-EM) can help scientists determine the three-dimensional structure of proteins in unprecedented detail. Jacques Dubochet, former group leader at EMBL, shared the 2017 ...

How do organic solar cells work on the inside? The answer lies in structures far too small to see—and difficult to access even with advanced techniques. So far, researchers have relied mainly on X-ray ...

Microscopy is an imaging technique that enables us to see a world that would otherwise be invisible to us. Once upon a time, visualizing cells, microbes and other entities not perceptible to the naked ...

Advanced light microscopy techniques are giving scientists a new understanding of human biology and what goes wrong in diseases Katarina Zimmer, Knowable Magazine Key takeaways: Super-resolution ...
