Nearly 10 months have passed since South Korea's first case of the novel coronavirus disease (COVID-19) was reported on January 20. The first patient, a 35-year-old woman from Wuhan, China, visiting ...

TEM works by transmitting a beam of electrons through an ultra-thin specimen. As the electrons interact with the specimen, they are scattered or transmitted, producing an image that is magnified and ...

Colorized scanning electron micrograph of a cell (blue) infected with SARS-CoV-2 (red), isolated from a patient sample. Image captured at the NIAID Integrated Research Facility (IRF) in Fort Detrick, ...

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 ...

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 ...

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 ...

Within cells lies an intricate, microscopic world that remains invisible to the human eye. To visualize cellular details, scientists rely on the power of electron microscopes. With unparalleled ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. Electron microscopy has existed for nearly a century, but a record ...

Cheese fungus, head lice, human sperm, a bee eye, a microplastic bobble: scientific photographer Steve Gschmeissner has imaged them all under the probing lens of a scanning electron microscope (SEM).

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 ...
