- If you think to gold bromide this is used as catalyst in organic chemistry or for the detection of ketamine.- A bromine/bromide mixture was proposed to extract gold from minerals.
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. Both are commonly used in analytical chemistry to manipulate or conceal certain chemical species during testing.
Fingerprints were first used as evidence linking suspects to crime in the late 19th century. Sir Francis Galton, a British scientist, was one of the pioneers in the study of fingerprints for identification purposes. The first documented use of fingerprints in a criminal case was in Argentina in 1892.

Fingerprints are used by law enforcement agencies for identification.
No, ammonium molybdate is not a base. It is a chemical compound commonly used in analytical chemistry for the detection of phosphates and silicates.

Used for error detection
They weren't used. They didn't know about fingerprints.
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.
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.

Fingerprints are used by (among many others) the FBI , Government, Police, banks, secure entry systems . . . , anywhere the unique characteristic of fingerprints can be used to identify a specific individual.
DNA and fingerprints are both unique to each individual and can be used for identification purposes. Both DNA and fingerprints are used in forensic investigations to link individuals to a crime scene. Additionally, both DNA and fingerprints are considered reliable forms of evidence in criminal investigations.
Fingerprints were first used to solve crimes in 1892, when they were instrumental in the conviction of a burglar in Argentina. This case marked the beginning of the widespread use of fingerprints as a forensic tool in criminal investigations.
