Electron Microscope


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 to name a few. All of
these use an electron microscope to further its research into its
field.

A general study that uses an electron microscope is microbiology, and
the findings from this goes on help medicine with applications in
biotechnology helping to produce antibiotics, vitamins, metals, and
proteins industrially.

Bacteriology, the study of bacteria, uses an electron microscope to
visualise viruses and then tries to determine what causes disease.
Samples of skin 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, 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 seen
if they derive from the genes of a person, and also the structure and
arrangement of chromosomes and DNA can be seen in clear detail.

Histology is the microscopic study of animal and plant cells, helping

Scanning Electron Microscope Essay

- In the forensic science field there are various machines used to examine physical evidence. One of those instruments is the scanning electron microscope (SEM). This instrument can be used in examining physical evidence found at crime scenes. There have been a number of scientists that have developed and improved the SEM. SEM is very significant in forensics because it can narrow down size, shape, and chemical composition. The scanning electron microscope is always growing and becoming a great impact on forensic science....   [tags: forensic science, evidence]

The Evolution of the Light and Electron Microscope Essay

- Birth of the Light Microscope In Circa 1000AD the first vision aid was invented (the inventor is unknown) it was called a reading stone. It was described as a glass sphere that magnified reading material when placed on top of an object. Someone picked up a piece of transparent crystal thick in the middle than at the edges, they looked through it, and realized it made objects look bigger. “Magnifying glasses” are mentioned during the first century A.D by Roman philosophers Seneca and Pliny the Elder, but never used much until the invention of spectacles, at the end of the 13th century....   [tags: evolution, eletron, light]

Electron Microscope Essay

- Electron Microscope The electron microscope has become one of the most widely utilized instruments for materials characterization. An electron microscope is a scientific instrument that allows us to “see” objects so small that they cannot be seen in any other way. (CITE) Electron microscopes have allowed scientists to see individual molecules and atoms for the first time. Most microscopes, including those in schools and laboratories today, are optical microscopes. They use glass lenses to enlarge, or magnify, an image....   [tags: science]

Essay on The Earliest Microscopes and Pond Ecology

- ... The revolving nose piece holds two or more objective lenses with different objective power. Many microscopes have Diaphragm or Iris control the intensity and size of light. All these parts in microscope help observe the specimen.                      Pond Ecology is the interaction of life in pond with environment. Pond have low oxygen levels, little animal life, and lack of food supply. A pond contains mostly water, few nutrients, and less aquatic life. Organisms live, grow, and die in the pond....   [tags: electron microscope, environment]

Essay on A Short Note On The Rejection And Passage

- 2.6. Rejection and Passage 119 To easily go on study, β2-Microglobulin (β2-MG) and human serum albumin were replaced by 120 lysozyme (LZM) and Albumin from bovine serum (BSA). LZM and β2-MG have the similar molecular 121 weight as LZM is 14 KDa while β2-MG is 11.8 KDa. The molecules of them are both positive charge 122 and globulin. At the same time, isoelectric point of them is relatively similar (LZM was 4.6 and β2- 123 MG 5.7). The molecular weight of BSA is 67 KDa while human serum albumin is 69 KDa....   [tags: Blood, Coagulation, Scanning electron microscope]

He attended Owens College in Manchester and was encouraged to apply for a scholarship to Trinity College at Cambridge University. He was accepted and later was chosen to be the third Cavendish Professor. Thomson 's discoveries made him one of the most accomplished physicists of his era. In 1906, he won the Nobel Prize in physics for his research on the discharge of electricity in gases.

Microscope Lab Report Essay

- Lab Work Not Included The purpose for completing this lab was to observe how microscopes function. The invention & evolution of the microscope has been an ongoing process since the Middle Ages, when the first convex magnifying lenses were introduced. In 1590, the Jansen Brothers invented the first compound microscope (two or more lenses).However, Antony van Leevenwenhoek created the first “true” microscope, in 1665, with 300x magnification & unbelievable resolution. During the late 1700’s, the microscope was reinvented with 1500x magnification....   [tags: Microscopes]

us learn more about what they are made from, what they do, how they do
it and how they live and eventually, die.

The study of plants, botany, 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.
