no there is not a better substance
Charcoal dust is usually effective to detect fingerprints. If not you could try Fingerprint spray.
It is simple
it would be charcoal dust that works better than iodine
Baking powder, baking soda, or iodine.
yes,yes there is
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.
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.
they could use something like: fingerprint spray or the super-glue trick
dont now
probably because iodine sticks to the oil from your fingers
