DescriptionNinhydrin is historically the most common reagent for processing fingerprints on porous substrates. It has been used as a fingerprint reagent since the 1950s but has been used as a cell stain since the early 1900s. Ninhydrin molecules form a complex with amino acids resulting in a purple product known as Ruhmanns purple. Purple fingerprints are easily visible on light-colored porous substrates but may be difficult to see on patterned or dark-colored substrates. DFO reacts with amino acids to produce a fluorescent product that is not readily seen with the naked eye. This makes it a useful reagent on dark or patterned porous items. DFO prints are viewed with an alternate light source or laser set to 530–570 nm (green light) through a red barrier filter. 1,2-indanedione is an emerging fingerprint reagent that results in visible pink fingerprints that are als...
