It has been used as a method to develop latent fingerprints on items of evidence. The fingerprints must be photographed as their visibility does not last. Iodine has been used when the evidence must not appear to have been examined, such as mail fraud cases where the fingerprints are developed and then the mail continues on it's way to allow authorities to trap the accomplice.

How do forensic scientists find fingerprints using iodine?
Forensic scientists use iodine fuming to detect latent fingerprints by sublimating solid iodine crystals, which react with oils and fats on the skin. The iodine forms a visible brown color on the fingerprint ridges, making them easier to visualize and collect as evidence.
Why doesn't solid iodine stick to finger prints?
Solid iodine sublimes, meaning it transitions directly from a solid to a gas without becoming a liquid. This property makes it difficult for iodine to leave residue on fingers when touched, which is why it doesn't stick to fingerprints.
Explain why the solid iodine did not stick to the finger prints but it could when it was heated?
Solid iodine sublimes at room temperature, meaning it goes directly from a solid to a gas without melting. As a result, it does not stick to surfaces like fingerprints because it does not become liquid when in contact with the skin. When heated, the iodine turns into a gas, which can then interact with the oils and sweat in the fingerprint, making it visible.
What is the common name for iodine?
The common name for iodine is iodine.
What is the difference between iodine and povidone iodine?
Iodine is a chemical element, while povidone iodine is a complex of iodine and the polymer povidone. Povidone iodine is commonly used as an antiseptic due to its slower release of iodine compared to pure iodine.
Why can gas iodine stick to fingerprints?
The gas iodine will stick to the fingerprints because they will crystallize when they come into contact with a cool surface. When heated, iodine directly changes into vapor.
