ELECTRON MICROSCOPIES Meaning and
Definition
-
Electron microscopy refers to a powerful set of imaging techniques that utilize electron beams to observe the structure and properties of materials at very high magnifications. It allows for the visualization of objects and details that are too small to be resolved by conventional light microscopes. Electron microscopes are capable of achieving resolutions in the range of a few nanometers, which is orders of magnitude higher than the limits of light microscopy.
There are two main types of electron microscopy: transmission electron microscopy (TEM) and scanning electron microscopy (SEM). In TEM, a beam of electrons is transmitted through an ultra-thin sample, and the resulting image is formed by detecting the electrons that pass through the sample. This technique is primarily used to visualize the internal structure and composition of specimens.
On the other hand, SEM involves scanning the surface of a sample with a focused electron beam and detecting the secondary electrons or backscattered electrons that are emitted from the surface. SEM provides detailed three-dimensional topographical information, allowing for the investigation of surface morphology, particle size, and elemental composition.
Electron microscopy has numerous applications in various scientific disciplines, including biology, materials science, nanotechnology, and medicine. It has been instrumental in advancing our understanding of cell structures, atomic arrangements in materials, surface chemistry, and the development of new materials. Furthermore, electron micrographs often provide valuable insights into the interactions and behaviors of complex systems at a microscopic level.

Etymology of ELECTRON MICROSCOPIES
The word "electron microscopies" is derived from two main components: "electron" and "microscopy".
1. Electron: The term "electron" originated from the Ancient Greek word "ēlektron", meaning "amber". Amber is a fossilized tree resin that had the property of attracting lightweight particles when rubbed, hence the connection to the concept of electrons. The electrical phenomenon connected to amber led to the use of the term "electron" to describe the subatomic particle with a negative charge.
2. Microscopy: "Microscopy" is derived from the Greek words "mikrós", meaning "small", and "skopéō", meaning "to look at" or "to observe". The combination of these words reflects the general meaning of "micro" and "scope" when referring to the study and observation of small objects.
