Introduction

Electron Microscope

Charmain McNulty

An electron microscope has many uses today, mainly to do with scientific study. The electron microscope has been developed to look at the tiniest structures, arrangements and components; it can magnify an object two million times.

It works by using electrons instead of light. The electrons can fit through smaller gaps in specimens creating a clearer magnified image. There are two types of electron microscope, a scanning electron microscope and a transmission electron microscope. A SEM creates a magnified image of the surface of an object, and a TEM produces a magnified image of a specimen.

Within the science of living organisms come the studies of bacteriology, cytology, histology and genetics

biopsies, to find diseases such as cancer. And as the electron microscope has improved, so has the health of the world’s population with diseases being diagnosed faster and more medicines and cures being made. Immunology and virology are other sciences linked with this.

Cytology, study of cells and their components uses the electron microscope to see entire structures or systems. Great developments, in this field, have been made due to the electron microscope. Morphology is similar to this study also.

Another science, genetics, has made great leaps and bounds in its findings thanks to the electron microscope. Diseases can now be

Conclusion

, has been aided with the electron microscope by botanists being able to find out more about ecology and therefore helping improve agriculture and horticulture.

Along with the above, the electron microscope is used in the study of many elements, for example crystallography, metallography and metallurgy.

The study of crystals looks at the actual arrangements of atoms in crystals, which in turn looks at the arrangement of atoms and molecules in many more substances and elements.

Metallography looks at the crystalline structure of metals and their alloys. This links to metallurgy, the science and art of adapting and processing metals to satisfy human demand. With the electron microscope, it can see defects caused and therefore repair and restore them to be the best for human consumption.
