What is masking and demasking agent?
A masking agent is a substance that can prevent the detection or identification of another substance in a sample. On the contrary, a demasking agent is used to uncover or reveal the presence of a masked substance for analysis or detection.

How is osmium used for microscopy fingerprint detection?
Osmium tetroxide (OsO4) is used in fingerprint detection. It is a strong oxidant and it reacts with unsaturated carbon-carbon bonds in lipids which are found in fatty tissue. It fixes biological membranes in tissue samples and also stains them. Osmium atoms have a very high electron density so such stained samples have a very high image contrast in electron microscopy.
Under what circumstances are DNA fingerprints used?
In most cases DNA fingerprints are used in identifying crime suspects. If there are fingerprints left at a crime scene then DNA fingerprints are used to attempt to identify the suspect. There is a database of criminal fingerprints that prints can be matched to if they are in the database.
