No, a Scanning Electron Microscope (SEM) cannot be used on living specimens because the high vacuum and electron beam used in an SEM would quickly kill the specimen. For observing living specimens, a different type of microscope, such as an optical microscope or a specially designed environmental SEM, should be used.
A scanning electron microscope (SEM) can be used to view nonliving specimens such as metals, ceramics, or other inorganic materials. It is not suitable for viewing living specimens due to the vacuum conditions and electron beam used in the imaging process.
I and II. Compound and dissecting microscopes can be used to view living samples due to their lower magnification and non-destructive imaging techniques. III and IV. Scanning and transmission electron microscopes are not ideal for viewing living samples as they typically require a vacuum environment and can damage the specimens.
An EM is basically of 2 types. Scanning Electron Microscope and Transmission Electron Microscope. Yes definitely it is used to magnify and resolve specimens but a living specimen cannot be used. Only dead are used. This is due to certain disadvantages that come along with this microscope. If need further details over the microscope uses and types then let me know.yea...i completely agree wif yuh... :)
Live specimens cannot be used in a transmission electron microscope (TEM) as the high vacuum environment and electron beam would quickly kill any living cells. Instead, biological specimens must be fixed, dehydrated, and stained prior to imaging in a TEM.
a TEM (transmission Electron Microscope) shoots electrons through the specimen and shows internal features of the cella SEM (scanning electron microscope) Electrons bounce off of the surface of the specimen, and show a 3d image of the surface on the specimen.a STEM (scanning tunneling electron microscope) uses a needle like probe shoots electrons from the inside out, shows 3D surface image CAN be used on living specimens

Transmission electron microscope

The electron microscope provides the highest magnification of preserved non-living specimens, allowing for detailed views at the cellular and even molecular level. Transmission electron microscopes (TEM) can achieve magnifications over 1,000,000x, while scanning electron microscopes (SEM) can provide detailed three-dimensional images at magnifications up to 500,000x.
A tunneling electron microscope cannot image live specimens.
According to the Encyclopdia Britannica, there are many kinds of electron microscopes:"The transmission electron microscope (TEM) can image specimens up to 1 micrometre in thickness. High-voltage electron microscopes are similar to TEMs but work at much higher voltages. The scanning electron microscope (SEM), in which a beam of electrons is scanned over the surface of a solid object, is used to build up an image of the details of the surface structure. The environmental scanning electron microscope (ESEM) can generate a scanned image of a specimen in an atmosphere, unlike the SEM, and is amenable to the study of moist specimens, including some living organisms.Combinations of techniques have given rise to the scanning transmission electron microscope (STEM), which combines the methods of TEM and SEM, and the electron-probe microanalyzer, or microprobe analyzer, which allows a chemical analysis of the composition of materials to be made using the incident electron beam to excite the emission of characteristic X-rays by the chemical elements in the specimen."More information about electron microscopes may be found on the Encyclopedia Britannica's website:http://www.britannica.com/EBchecked/topic/183561/electron-microscope
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.
Live specimens cannot be used in a transmission electron microscope (TEM) as the high vacuum environment and electron beam would quickly kill any living cells. Instead, biological specimens must be fixed, dehydrated, and stained prior to imaging in a TEM.
An electron microscope requires that the subject be dead to function. In order to receive a picture, the specimen must be coated in chemicals and put into a vacuum, a process which will kill any living specimen. A light microscope, although not as detailed, will allow the scientist to observe living specimens.
