Ninhydrin is a chemical used to detect ammonia or primary and secondary amines. When reacting with these free amines, a deep blue or purple colour known as Ruhemann’s purple is produced.
Ninhydrin in solution is commonly used by forensic investigators in the analysis of latent fingerprints on porous surfaces such as paper. Amino acid containing fingermarks, formed by minute sweat secretions which gather on the finger’s unique ridges, are treated with the ninhydrin solution which turns the amino acid finger ridge patterns purple and therefore visible.
