Image of pollen grains taken on a SEM shows the characteristic depth of field of SEM micrographs M. von Ardenne's first SEM SEM with opened sample chamber Analog type SEM. A scanning electron microscope (SEM) is a type of electron microscope that produces images of a sample by scanning the surface with a focused beam of electrons.
Scanning electron microscopy (SEM) images of C. lusitaniae on filament-inducing media. Cells grown on V8 (pH = 7) media for 7 days at 37 °C were processed for SEM, and imaged (see Materials and Methods). Scale bars for upper panel (1000x) and lower panel (5000x) images represent 10 μm and 2 μm, respectively.
SEM image of the shell micro-scale structure of OL-ecophenotype Notodiscus hookeri. The round white dot marks the outer periostracum. The almost vertical white line shows the organic layer. The thick white line is the innermost mineralised layer. Scale bar is 10 μm. SEM image of the shell structure of OL-ecophenotype Notodiscus hookeri. The ...
CryoSEM of biological samples with a high moisture content can be done faster with fewer sample preparation steps than conventional SEM. In addition, the dehydration processes needed to prepare a biological sample for a conventional SEM chamber create numerous distortions in the tissue leading to structural artifacts during imaging.

The EyeWire project harnesses human computation in a game to trace neurons through images of a volume of retina obtained using serial block-face scanning electron microscopy. [ 7 ] Many different samples can be prepared for serial block-face scanning electron microscopy and the ultramicrotome is able to cut many materials, therefore this ...
