Electron microscopy; Scanning Electron Microscopes (SEM) and Transmission Electron Microscopes (TEM). The vacuum required for electron microscopy to work correctly precludes the observation of living organisms. Biological samples must be dried then coated with a conductive metal.

What is the definition of the term fluorescence microscopy?
The term "fluorescence microscopy" is a type of light microscopy in which the specimen is irradiated at wavelengths that excite fluorochromes. In medicine, it is used to detect antigens.
Light microscopy and electron microscopy differences in practical use?
Electron microscopy gives higher resolution, but it's expensive, slow, and cumbersome. And for many things, it's not needed.
What is chemo microscopy?
Chemo microscopy is the use of chemical reagents to examine or identify a crude drug with the help of a microscope
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.
Simple staining is often necessary to improve contrast in what microscope?
The type of microscopy that uses chemical stains to add color and increase contrast is light. The type of microscope that can be used to observe very small surface details is called a scanning electron.

What is the differences between light reflection and light transmission microscopy?
Transmission microscopy and reflection microscopy refer to type of illumination used to view the object of interest in the microscope. Reflected light microscopy, also called episcopic illumination or just epi-illumination, uses top-down lighting to illuminate the specimen and the light is reflected back from the specimen to the viewer. This type of illumination is most often used with opaque specimens like metallurgical samples. Transmitted light microscopy, also called diascopic illumination, uses bottom-up illumination where the light is transmitted through the specimen to the viewer. This type of illumination is most often used with translucent specimens like biological cells.
