The Electron Microscopy shared resource offers techniques that allow researchers to resolve structures from cellular ultrastructure all the way down to molecular interactions. Our expertise in EM ...

There are two main types of electron microscopes: Transmission Electron Microscopes (TEM) and Scanning Electron Microscopes (SEM). In a TEM, electrons pass through the sample, creating highly ...

The family of electron microscopy techniques have become staple methods for imaging nanoscale objects, including nanoparticles, viruses and proteins.The appeal of electron microscopy as a ...

For example, interactions of the electron beam with specific gases can be used to achieve the controlled deposition of materials such as metals or different forms of carbon onto a substrate. This ...

Michigan Tech’s new Scanning Transmission Electron Microscope lets researchers zoom in to understand the big picture at the atomic scale. Housed in a specially constructed brick building at the south ...

The electron beam follows a vertical path through the microscope, which is held within a vacuum. The beam travels through electromagnetic fields and lenses, which focus the beam down toward the sample ...

W ith 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 ...

Transmission Electron Microscopy unveils atomic-level details across materials science, biology, and nanotechnology. Unveil nanostructures unseen to other microscopes. Home; ... the entire image is ...

Proteins from 40 kDa to several MDa in size can be studied by this methodology. Very little sample is required for this technique. For cryo-EM the specimen, typically a purified protein sample, is ...

While the original electron microscope arrived in the early 1930’s (there’s still a controversy to this day over who invented the very first one), scientists have relied on what are known as ...

[Max Knoll] and [Ernst Ruska], in fact, developed the transmission electron microscope or TEM. The TEM works by passing an electron beam through a very thin sample and detecting it on the other side.

Specifically, the electron detector is designed for use in a scanning electron microscope, which is typically used for inspecting the surface of a sample and retrieving a high-resolution, 3D image ...
