NCIt definition : Technique of electron microscopy in which the specimen is coated with heavy metal
and then scanned by an electron beam. The resolution is not as great as with transmission
electron microscopy, but preparation is easier (often by fixation followed by critical
point drying), the depth of focus is relatively enormous, the surface of a specimen
can be seen (though not the interior unless the specimen is cracked open) and the
image is aesthetically pleasing.;
Alternative definition : CDISC: An electron microscopy imaging technique that is utilized to examine structural
components of a sample by passing electrons through a specimen that has been coated
with a heavy metal.;
