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 ...

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 ...

"The electron microscope has been used in hair research for half a century, but the knowledge gained through this study has become rather fragmented over the years. While the molecular biological ...

Researchers have shown that expensive aberration-corrected microscopes are no longer required to achieve record-breaking microscopic resolution. Researchers at the University of Illinois at ...

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 ...

New NE-AFM method measures nuclear stiffness in living cells. It shows cancer nuclei change softness with chromatin and environment, aiding diagnosis and treatment. By employing a technique called ...
