Charcoal dust is usually effective to detect fingerprints. If not you could try Fingerprint spray.
Baking powder, baking soda, or iodine.
It is simple
yes,yes there is
it would be charcoal dust that works better than 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.
An iodine solution is used.
yes its ok but there mabey better ways
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.
When iodine is added to cornstarch, a blue-black complex is formed. This is utilized as a simple test to detect the presence of starch in a given substance.
they could use something like: fingerprint spray or the super-glue trick
