Can the electron microscope be used to study a live specimen and why?

Not really. An electron microscope requires that the specimen be placed in a vacuum for viewing. It would most certainly kill any living creature placed inside it. No, the specimen being viewed is incapible of life after being placed into the slit.

The reason why electron microscopes cannot be utilized to study living organisms is because these microscopes require a vacuum, or a container devoid of matter (including air), to function. This is to prevent the electrons from bumping into molecules in the air, like oxygen molecules, and producing false images. Living things can't survive in vacuums.

Advantages and disadvantages of light microscope over electron microscope?
they are relatively smaller, electron ones are biggerthey are easy to usethey allow you to see coloured images, electron ones don'tyou can observe live specimen, specimen has to be dead with electron microscopesi was trying to view the answer in relation to transmmission
Electron microscope would be used if?
We need to study the details of a bacterium or virus
Which type of microscope can observe non-living cells?
A tunneling electron microscope cannot image live specimens.
What Microscope that gives 3-D image?
There are at least two types of microscope that can give 3D images. Confocal microscopes that use lasers to illuminate the object and scanning electron microcopes (SEM) that use an electron beam. A SEM can give better magnification than confocal but confocal can image live moving subjects. In SEM the object of intrest must be coated with gold so only dead things can be imaged.
Does lithium have a live electron cloud?
No.
Can the light microscope be used to study a live specimen?
Yes, a light microscope can be used to study organsims.
When is it better to use a light microscope rather than an electron microscope?
When you need to observe a live specimen

What is the difference between ordinary microscope and electron microscope?
Magnification and resolution is in light microscope is about 500x and 0.2micro metres respectively than human eye.In e.microscope magnification is about 200,000x and resolution is 0.0005micro metres. You cannot observe live specimen through electron microscope. Lenses in light microscope are glass while e.microscope use magnetic lenses. E.microscope is relatively very larger than light microscope. You need special knowledge to handle electron microscope. You can observe through naked eye in e.microscope. A beam of electrons is sent through specimen in e.microscope.In light microscope a beam of light is sent. Electron microscope is very complex relative to light microscope.

We need to study the details of a bacterium or virus
How would you distinguish between the light microscope and the electron microscope?
Light microscopes can use live cells and are much smaller than electron microscopes
Which type of microscope can observe non-living cells?
A tunneling electron microscope cannot image live specimens.
What are the advantages of an electron microscope over a light microscope?
An electron microscope can reach a far greater magnifiction than a conventional microscope. It is obvious that the largest advantage of any type of microscope is to observe an organism that can not be seen by the unaided eye. Light microscopes are easy to use, can magnify up to 2000 times, enable magnification of live cells and their movement, and are relatively cheap compared to electron microscopes. The only disadvantage is that it can only magnify up to 1000 times, after that the image is blurry, whereas an electron microscope can magnify up to 100,000 times! However, electron microscopes are extremely expensive, difficult to use, and cannot observe live specimens.

Why did James and Albert invent the electron microscope?
if you wanne find me i live in bankok and go to bakok patana school see you there!!
What objective is used when observing fresh specimen?
The objective of observing fresh specimen is to find out how the still-live specimen functions. One can observe blood flow and movement.
Can live speciments be examinednwith an electron microscope?
No. The is the big drawback to SEM and TEM microscopy, the subjects must be fixed to the slide, fractured or some other preparation method and this means they must be dead.
