A scanning electron microscope (SEM) can be used to view a wide range of specimens including metals, minerals, ceramics, plastics, biological samples, and some polymers. These specimens can be studied at high magnifications and provide detailed information about their surface topography and composition.

Can a Scanning Electron Microscope be used on living specimens?

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.


What type of microscope can only be used to view nonliving specimen?

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.


Which type of microscope would be used to observe structures on the surface of an individual cell?

A scanning electron microscope (SEM) would be used to observe structures on the surface of an individual cell. SEM uses a focused beam of electrons to scan the surface of a sample, producing high-resolution images of the surface features of the cell.


Which microscope would be MOST useful for examining the contours of the surface of a bacteria cell?

It depends on the type of biofilm, what surface the biofilm is on, and what information you want to get by looking at the biofilm under a microscope. If you just want to look at how much of a surface is covered by a biofilm, you can use normal light trasmission microscopy (as long as the surface is transparent e.g. glass). Alternatively you could use epifluorescent microscopy in combination with a fluorescent stain. If you want to look at the structure of the biofilm, confocal laser scanning microscopy is probably the best as you can get a 3D image. Other useful types of microscopy include phase contrast and DIC, which allow you to look at the biofilm without staining it first.


What type of microscope you used to observe the pores of skin?

A scanning electron microscope (SEM) is often used to observe pores of the skin due to its high resolution and magnification capabilities. This type of microscope allows for detailed imaging of the surface features of the skin at a micro or nanoscale level.

Compare the process used to produce a TEM and an SEM?

The process used to produce TEM will cut cells and tissues in to ultra-thin slices so that they can be viewed under the microscope. However, the ones on SEM do not need to be cut as they can easily be visualized.

How are TEM and SEM microscopes different from compound microscopes?

TEM (transmission electron microscope) and SEM (scanning electron microscope) use electron beams instead of light to magnify specimens, providing higher resolution images. Compound microscopes use visible light and lenses to magnify specimens. TEMs transmit electrons through the specimen to create an image, while SEMs scan the specimen's surface with electrons to generate an image.

What type of microscopes do scientist use when they want to examine specimens that are smaller than those which can be seen using a light microscope?

Scientists use electron microscopes, such as transmission electron microscopes (TEM) and scanning electron microscopes (SEM), to examine specimens that are smaller than what can be seen using a light microscope. These microscopes use beams of electrons instead of light to achieve higher resolution and magnification, allowing scientists to observe structures at the nanoscale.
