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 ...

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 ...

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 ...

Felipe Rivera, director of the microscopy facility at BYU, stands in front of one of the university’s new transmission electron microscopes, which will allow undergraduate students to capture 3D ...

In transmission electron microscopy (TEM), where the electron beam passes through the sample to be directly imaged on the detector below, it is often necessary to support the thin samples on a grid.

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 ...
