it would be charcoal dust that works better than iodine
yes,yes there is
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.

A method of studying fingerprints to establish identification.(finger prints)
The study of fingerprints as a method of identification.
Fingerprints are unique to each individual and are formed by the ridges and patterns on the skin of the fingertips. No two people have the same fingerprints, making them a reliable method for identification. The patterns of ridges, known as loops, arches, and whorls, are what distinguish one person's fingerprints from another's.
Filtration because iodine is not soluble in water.
When an analyte that is a reducing agent is titrated directly with a standard iodine solution, the method is called "iodimetry". When an analyte that is an oxidizing agent is added to excess iodide to produce iodine, and the iodine produced is determined by titration with sodium thiosulfate, the method is called "iodometry".
That is the correct spelling for the word "method" (technique, process).
