Electron microscope Nowadays the electron microscope has many uses, mainly related to scientific study. The electron microscope was developed to observe the smallest structures, arrangements and components; it can magnify an object two million times. It works by using electrons instead of light. Electrons can pass through smaller gaps in samples creating a clearer magnified image. There are two types of electron microscope, a scanning electron microscope and a transmission electron microscope. An SEM creates a magnified image of the surface of an object, and a TEM produces a magnified image of a sample. The science of living organisms includes the studies of bacteriology, cytology, histology and genetics, to name a few. All of these use an electron microscope to further research in their field. A general study using an electron microscope is microbiology, and the resulting results help medicine with applications in biotechnology that help produce antibiotics, vitamins, metals, and proteins at an industrial level. study of bacteria, uses an electron microscope to view viruses and then tries to determine what causes the disease. Skin samples can be taken from people and studied with an electron microscope, known as biopsies, to find diseases such as cancer. And as the electron microscope has improved, the health of the world's population has also improved: diseases are diagnosed more quickly and more medicines and treatments are produced. Other sciences related to this are immunology and virology. Cytology, the study of cells and their components, uses the electron microscope to see entire structures or systems. Great developments in this field have been made thanks to the electron microscope. The morphology is also similar to this study. Another science, genetics, has made great strides in its discoveries thanks to the electron microscope. It is now possible to observe diseases if they arise from a person's genes, and even the structure and arrangement of chromosomes and DNA can be observed clearly and in detail. Histology is the microscopic study of animal and plant cells, which helps
