A general term for a chemical that makes a specimen visible is a stain. There are many types of stains available, depending upon the structure you want to visualize and the type of microscope you want to use, e.g. fluorescent stains like DAPI for fluorescence microscopy, or hematoxylin and eosin (H and E) staining for brightfield microscopy.
Immersion oil
This compound is the methylene blue.
These substances are called staining agents; for example methylene blue.

An example is methylene blue.
Methylene blue is an example.

Stain
In standard light microscopes, no chemical is used; subjects are observed by light projected from underneath the stage, which light up whatever is on top. Most microscopes allow amount of light to be adjusted (usually both the power of light projected and an aperture to control the exposure), and at lower settings things that are "harder to see" with more light become visible. Occasionally, under regular circumstances whatever your studying, some kind of bacteria, for instance, may be difficult to see. In this case, you might stain the bacteria, especially to highlight certain aspects of it (cell wall, for example). However, again, this is not a chemical in the microscope but with the subject itself - the microscope is the same as it always was.

The general term is 'stain' of which there are several chemicals that can be used, depending on the specimen.
Methylene blue is an example.
The term for visible with the unaided (naked) eye is "gross", as in gross anatomy.
A stain of a contrasting color used to color the components in a microscopic specimen that are not made visible by the principal stain.
used to poke and make easier to examine a specimen

Calcium is the chemical or rather the mineral that is used to make teeth.
Immunohistochemistry is a lab technique where a slide is made from a slice of tissue. It is treated with an antibody against the protein of interest that is made to bind to the protien with one end and and have a chemical reaction on the other. The chemical reaction can then be used to make the protein visible under the microscope.
