Until now. Two laboratories recently used cryo-electron microscopy to directly image atoms in a protein molecule with a resolution of about 1.2 x 10-7 millimeters or 1.2 ångströms. The previous ...

Much like the traditional scanning electron microscope (SEM), the field emission scanning electron microscope uses electrons to illuminate a sample, instead of visible light as is used in optical ...

A team of researchers at the Medical Research Council Laboratory of Molecular Biology, in the U.K., has re-examined an old ...

Electron microscopy uses a beam of electrons to illuminate a sample and achieve much higher spatial resolution than light microscopy. Transmission electron microscopy generates an image of the ...

The FEI Philips XL 40 Environmental Scanning Microscope (ESEM) is a large-chamber, tungsten source, environmental scanning electron microscope capable of high and low vacuum imaging. The FEI Philips ...

Cryoelectron microscopy is a method for imaging frozen-hydrated specimens at cryogenic temperatures by electron microscopy. Specimens remain in their native state without the need for dyes or ...
