Cryo Field Emission Scanning Electron Microscopy [PDF]
BioTechniques, 2001 Low-temperature scanning electron microscopy (cryoSEM) was introduced in the early 1970s, shortly after the appearance of the first commercial scanning electron microscopes. This technique has been utilized widely in plant biology, the food and paper industry, X-ray analytical studies, and material sciences (8).
