Ninhydrin Fingerprint Definition at Johanna John blog

Ninhydrin Fingerprint Definition. For well over ten years, many of the federal, state, and city crime laboratories have used the ninhydrin technique for the development of latent. Ninhydrin is the most widely used chemical reagent for the detection of latent fingermarks on porous surfaces such as paper and cardboard. Ninhydrin is the most preferred chemical for the visualization of fingerprints on porous materials and paper as it reacts with the amino acids in the sweat left behind in a fingerprint. Ninhydrin, as well as its analogues, reacts with. Ninhydrin is now the most widely used method for developing latent fingerprints on paper surfaces. Latent prints can be found on all types of. The strong compound formed by ninhydrin is called ruhemann’s purple. The first published suggestion that ninhydrin could be used for fingerprint detection was made by oden and von hofsten in 1954 [4] based on observations. Other contaminants found in prints result from contact with different materials in the environment.
