GENERAL HISTOLOGY

Detailed explanation-1: -Scanning electron microscopy (SEM) is normally used for imaging the surface of cells, tissues and whole multicellular organisms. SEM images of surfaces appear to be three-dimensional (3D) but there is no measurable depth information in the image.

Detailed explanation-2: -The scanning electron microscope (SEM) lets us see the surface of three-dimensional objects in high resolution.

Detailed explanation-3: -The SEM is a microscope that uses electrons instead of light to form an image. Since their development in the early 1950’s, scanning electron microscopes have developed new areas of study in the medical and physical science communities. The SEM has allowed researchers to examine a much bigger variety of specimens.

Detailed explanation-4: -SEMs are used in materials science for research, quality control and failure analysis. In modern materials science, investigations into nanotubes and nanofibres, high temperature superconductors, mesoporous architectures and alloy strength, all rely heavily on the use of SEMs for research and investigation.
