The microscope is inexpensive and easy to use is an advantage of electron microscopy. High resolution images of both biological and non-biological specimens can be obtained using the electron microscopy (EM) technique. In order to fully understand the structure of tissues, cells, organelles, and macromolecular complexes, it is employed in biomedical research.
There are various kinds of electron microscopes, such as the scanning electron microscope (SEM), the transmission electron microscope (TEM), and the reflection electron microscope (REM.). Magnification and better resolution are possible thanks to the utilization of electrons as opposed to light waves, allowing for the analysis of structures that would otherwise be invisible.
