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
...in the fields of both science and medicine, future epidemics of any disease can be handled better. When a lethal disease begins to rampage a population, research on similar epidemics can help the world contain, cure, and prevent the disease to protect the world and its population.
Animals organ system share similar characteristics with humans, both bodies perform many vital functions such as breathing, digestion, movement, sight, hearing and reproduction. Making it easy for scientist to understand how living things work and how to treat disease when the body falls ills to put it back to its right stage. Also a great amount of knowledge of the body anatomy and functions, had been made with the use of animal testing.(Understanding Animal Research) Researchers had been able to find new cure...
One definition of a microscope is "an optical instrument that uses a lens or a combination of lenses to produce magnified images of objects." Holden Caufield can be symbolized by a microscope and its parts: the field of view, the focus, and the magnifier.
Gunpowder, the vaccine, blood transfusion, the telescope, surgery, the submarine, the barometer, the submarine, and the microscope are all great inventions that helped change the way people live today. They are some of many scientific inventions that changed the way of life for people.
Every organ in the human body is composed of one or more tissues. The study of these tissues is known as histology. It is because of histology that the structure of organs can be researched and understood. Since organs are composed of tissues, it is important to understand each tissue type, their structure, their location, and their functions to better understand how each organ operates within the human body.
Spectroscopy Spectroscopy is the study of energy levels in atoms or molecules, using absorbed or emitted electromagnetic radiation. There are many categories of spectroscopy eg. Atomic and infrared spectroscopy, which have numerous uses and are essential in the world of science. When investigating spectroscopy four parameters have to be considered; spectral range, spectral bandwidth, spectral sampling and signal-to-noise ratio, as they describe the capability of a spectrometer. In the world of spectroscopy there are many employment and educational opportunities as the interest in spectroscopy and related products is increasing.
the bulk to ordinary matter; the volume of an atom is nearly all occupied by the
Medicine is one area that constantly looks to use prior knowledge to discover new things. Take the HeLa cells for instance. The initial discover of these cells occurred in 1951. These cells came from a black woman named Henrietta Lacks. She was diagnosed with cervical cancer. He doctor took a segment of her tumor and sent it to Dr. George Otto Grey, who was the first scientist to successfully grow human cells in a culture. These cells would go on to be used in research for cloning, the polio vaccine, gene mapping and in virto fertilization. These cells were important to science because no scientist had an endless supply of cells ...
An oscilloscope is an electronic test instrument that is used to observe an electronic signal, typically voltage, as a function of time. In other words, it is a voltage versus time plotter. Oscilloscopes come in two basic types, analogue or digital, and support various features and functions useful for measuring and testing electronic circuits. An oscilloscope is a key piece of test equipment for any electronics designer.
Histopathological samples are examined in vivo where the relationship between the cells is maintained and observable. These can be cross sections of small organs or slices of larger ones. This results in a large number of cells being available and their cell-to-cell interactions apparent for examination.
Instrumentation is the branch of engineering that deals with measurement and control. The instrument that is used for the determination of concentration of trace metals is AAS (Atomic Absorption Spectrophotometer). The official definition of instrumentation- is a collection of instruments and their application for the purpose of observation, measurement and control [23].
Because cells are the ‘basic unit of life’, the study of cells, cytology, can be considered one of the most important areas of biological research. Almost every day on the evening news, we are told about new discoveries in cell biology, such as cancer research, cloning, and embryology.

Medical laboratory technologists, also known as histotechnologists, work in a laboratory environment diagnosing diseases, doing research, or instructing others. Histotechnologists detect tissue abnormalities and treatments for the diseases causing the abnormalities, a vital role in the allied health profession. Histotechnologists prepare very thin slices of human, animal, or plant tissue in order to examine it using a microscope. This is considered one of the most important parts of the complicated process of medical investigation used to establish and confirm a diagnosis.
Nowadays, engineering has been reduced to something less than simple. It’s still a hard and long process, but it has been made a lot more efficient. Smaller and smaller innovations and inventions are being made. Small, paper thin, portable microscopes, water wheels, and devices that can display yo...
Microtome is an instrument for cutting thin sections of a tissue, for microscopic examination. Microtomes will advance an object for a predetermined distance then slide the object to the cutting tool. There are a few types of microtome such as freezing microtome which is used for cutting frozen tissues, rotary microtome which is the one in which wheel action is translated into a back-and-forth movement of the specimen being sectioned and sliding microtome in which the specimen being sectioned is made to slide on a track.
