Transmission Electron Microscopy

Transmission electron microscopy (TEM) is a powerful and widely used tool that allows researchers to observe the inner structures of cells and other small objects at extremely high resolution. TEM is a type of electron microscopy that uses a beam of electrons to create an image of the sample being studied. The electrons are passed through the sample, and the resulting image is then magnified and displayed on a monitor. TEM is used in a wide variety of scientific fields, from biology and medicine to materials science and engineering. TEM allows researchers to study the structure and composition of cells and other objects down to a very small scale, on the order of nanometers. This means researchers can observe individual molecules, atoms, and even some subatomic particles. For example, researchers can use TEM to observe the structure of a virus, the arrangement of DNA molecules, or to study the behavior of individual atoms in a crystal. TEM can also provide information about the chemical composition of an object, as the electrons are scattered by the material in different ways depending on what elements are present. TEM can be used in many different ways, such as to examine the structure of materials, observe cellular processes, measure the size and shape of objects, and determine the chemical composition of a sample. TEM can also be used to analyze the structure of a material at various temperatures, as well as to study the effects of different treatments on a sample. TEM is a powerful and versatile tool that has revolutionized the fields of biology, medicine, and materials science.
