Forensic
When staining, Oil Red O can make fat more visible in various cuts in pathology.
It is also used in a technique (the method is called as the dye: Oil Red O), discovered in 2004 by Alexandre Beaudoin, for staining latent fingerprints. This technique allows the development of latent fingerprints on porous exhibits (such as paper, cardboard, etc.) that are dry or wet.
It mainly targets fat deposits on the surface of porous exhibits. It is a non-destructive technique (which does not destroy the exhibit and doesn’t prevent the use of other techniques).
It is a safe alternative to the Physical Developer method, and is also used in sequence with other methods of fingerprints development.
