Explanation:
Detailed explanation-1: -A scanning electron microscope (SEM) directly produces an image of the three-dimensional structure of the surface of a specimen.
Detailed explanation-2: -Electron microscopy (EM) is a technique for obtaining high resolution images of biological and non-biological specimens. It is used in biomedical research to investigate the detailed structure of tissues, cells, organelles and macromolecular complexes.
Detailed explanation-3: -Immuno-electron microscopy can reveal locations of proteins with nanometer resolution but is limited by the quality of fixation, the paucity of antibodies, and the inaccessibility of the antigens.
