Quizplus · Accepted Answer

Scanning electron microscopy (SEM) is used to view the surfaces of objects and generates a three-dimensional image. Positive staining, negative staining, shadow casting, and freeze-fracture freeze-etch are all techniques used in transmission electron microscopy (TEM), which is not suitable for surface imaging.
