For a scanning electron microscope, the most commonly used type of EM, there is no need to do anything other than stick it to an electrically conducting pad. If the sample is particularly insulating, it may be worth coating it with a very thin gold layer to prevent the specimen from charging up with electrons from the beam (this would blur the image)
For a transmission electron microscope, the specimen is most commonly encased in epoxy resin before being sliced into thin enough slices that the electron beam can pass through. The sample is then placed on a fine copper grid before being placed in the microscope.

How do you prepare specimen for stereo microscope?
To prepare a specimen for a stereo microscope, first place it on a clean glass slide. If needed, add a drop of water or mounting medium to help stabilize the specimen. Then cover the specimen with a coverslip, to protect it and ensure clearer imaging under the microscope. Finally, position the slide on the stage of the stereo microscope and adjust the lighting and focus for optimal viewing.
Is what you look at under a microscope called a specimen?
Yes - but a specimen can be something that is not observed under a microscope as well. For example, if you ever went on a walk in the country, picked a wildflower that grew there, and brought it home, you would have a specimen of a native plant that grew in the area where you found it.
How to do a wet mount slide preparation?
To prepare a wet mount slide, place a small drop of liquid or specimen in the center of a clean microscope slide. Gently lower a coverslip onto the drop at a 45-degree angle to avoid trapping air bubbles. View the specimen under a microscope on low power to observe.
How do you prepare a wet mount slide for the microscope?
Take a clean slide (either depressed or flat) and add a drop of water using an eye dropper. Add the specimen and using the slip cover, touch the end of the slip cover to the water. Lay flat as smoothly as possible to omit bubbles from forming.
Why can't you view living cells through electron microscope?
"In electron microscope the object is viewed in highly vaccum conditions. Living cells would disentegrate in such a condition." This answer is not mine it comes from the "why can't electron microscopes be used to view cell structures" question
How must samples be prepare for observation by electron microscope?
They must be preserved and dehydrated. Once this is accomplished, put the specimen onto a slide, and then the slide is ready to be viewed under the microscope.

How would you prepare a amoeba specimens for observation?
To prepare an amoeba specimen for observation, you would first collect a sample containing the amoebas. Then, place a drop of the sample on a microscope slide and cover it with a coverslip. Finally, observe the specimen under a microscope, adjusting the focus to see the amoebas clearly.
What are the steps involved in preparing a wet mount of a specimen?
To prepare a wet mount of a specimen, first, place a small drop of liquid (like water or a suitable medium) on a clean microscope slide. Next, using a pair of tweezers, carefully place the specimen in the drop. Then, gently lower a coverslip at an angle over the specimen to avoid air bubbles. Finally, observe the specimen under a microscope, adjusting the focus as needed.
Why glycerin is used to prepare a temporary mount?
Glycerin is used to prepare a temporary mount because it has refractive properties that make the specimen more translucent and easier to see under a microscope. It also helps to preserve the specimen for a short period of time without causing damage.
What are the Kinds of microscopes and their uses?
There there are many. Simple microscope, compound microscope, light microscope, scanning electron microscope, TEMicroscope, Dissection microscope, etc and most of them are used to see small cells that cannot be seen by the naked eye.

How do you prepare a wet mount?
To prepare a wet mount, place a small drop of liquid or specimen on a slide. Then, gently lower a coverslip onto the drop at a slight angle to avoid trapping air bubbles. This creates a thin layer of liquid between the slide and coverslip for viewing under a microscope.
What precautions should be taken if you are observing a live organism under a microscope?
When observing live organisms under a microscope, ensure that the microscope is properly clean and sterilized to prevent contamination. Handle the organisms gently to avoid harming them, and use appropriate magnification and lighting to clearly observe the specimen without causing stress or damage. Be cautious with any equipment or reagents used to prepare the slide, and follow safety protocols to protect yourself and others from any potential hazards.
