Answer Fingerprints will show up on just about anything.
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.
Ninhydrin is another common chemical used to develop fingerprints on porous surfaces like paper. It reacts with amino acids found in sweat to produce a purple color, making fingerprints visible. Magnetic powder and fluorescent powders are also effective alternatives to iodine for developing fingerprints on different surfaces.
