ELECTRON MICROSCOPY Meaning and
Definition
-
Electron microscopy is a scientific technique that utilizes a beam of electrons to observe and analyze the structure and composition of materials at a microscopic level. It is an advanced imaging technique that provides higher resolution and greater clarity compared to traditional light microscopy.
In electron microscopy, a sample is prepared and placed under a vacuum inside an electron microscope. This instrument consists of an electron gun that emits a beam of electrons, which is then directed towards the sample. The electrons interact with the atoms constituting the material, resulting in various interactions such as scattering and absorption. These interactions produce signals that are collected and converted into an image by various detectors.
Electron microscopy can provide detailed information about the morphology, topography, and even elemental composition of a wide range of samples, including biological specimens, cells, tissues, minerals, and various materials. Different modes of electron microscopy, such as transmission electron microscopy (TEM) and scanning electron microscopy (SEM), offer unique advantages and are used for different purposes.
TEM involves transmitting the electron beam through an ultra-thin sample, allowing for detailed imaging of internal structures and analyzing the crystallography of the material. On the other hand, SEM scans the surface of a sample, providing information about the sample's three-dimensional structure and surface morphology.
Electron microscopy has revolutionized numerous scientific disciplines, from biology and medicine to materials science and nanotechnology, enabling scientists to explore and understand the intricate details of objects on a nanoscale level.

Etymology of ELECTRON MICROSCOPY
The word "electron microscopy" is derived from two main components: "electron" and "microscopy".
1. "Electron": The term "electron" comes from the Latin word "electrum" which means "amber". The Greek word "ἤλεκτρον" (elektron) also refers to amber. In the late 19th century, the term "electron" was coined by physicist G. Johnstone Stoney to describe small, negatively charged particles that he believed to be fundamental units of electric charge.
2. "Microscopy": The word "microscopy" is derived from the Greek words "μικρός" (mikros) meaning "small" and "σκοπέω" (skopeo) meaning "to look at". Combined, "microscopy" refers to the technique of examining objects or samples at a microscopic level.
