Sample Preparation for Scanning Electron Microscopy

 · Proper sample preparation plays an important role in obtaining the required information when using scanning electron microscopy (SEM). You need to consider the sample's size, shape, state, and conductive properties prior to sample preparation. Ideally, the smallest representative sample size is the one to use. The microscope's detection capacity is as much as 1µm from the sample surface.

[PDF] Scanning Electron Microscopy

The technology of scanning electron microscopy (SEM) is described in brief. Its application to the study of cell and tissue structure is demonstrated and the evolution of the concept of "topographical histology" is discussed. Some current literature on the application of SEM is reviewed under the headings of experimental pathology and human pathology. While SEM has become an indispensable.
