Ninhydrin-based Forensic Investigations I. Fingerprints
نویسندگان
چکیده
Ninhydrin reagents are currently used for amino acid determination. However, ninhydrin reacts with amino groups of amino acids and other components of palmar sweat to develop Ruheman’s purple. Therefore, it was used on a large scale to fingerprint development. Another recent application of ninhydrin is related to trace cyanide detection and determination. However, this simple compound may have multiple applications in peptide and protein research, in drug identification and detection or in heterocycle synthesis. Mainly, detection of finger marks with ninhydrin at a crime scene is of prime interest for forensic investigators. Herein, we review the most significant forensic applications of ninhydrin and its derivatives.

Recently, a novel ninhydrin reaction with cyanide has opened new ways to detect this poison in the body fluids and the environmental samples. Mainly, detection of cyanide with ninhydrin at a crime scene could be of prime interest for forensic investigators. Besides, the reaction conditions are very common, except the need to avoid oxygen and oxidizers. The ninhydrin-based assay proved to be hig...
متن کاملThe quantification of fingerprint quality using a relative contrast index.
Research into fingermark enhancement techniques has traditionally used visual comparisons and qualitative methods to assess their effectiveness based on the quality of the developed fingermark. However, with increasing research into the optimisation of these techniques the need for a quantitative evaluative method has arisen. Parameters for acceptable fingerprint quality are not well defined an...

Previous work by the authors [1] investigated the recoverability of fingerprints on paper which had been exposed to elevated temperatures by comparing various chemical enhancement techniques (ninhydrin, 1,8-diazafluoren-9-one (DFO), and physical developer (PD)). During that study, it became apparent, as a consequence of
متن کاملUsing ninhydrin to detect gravesoil.
Some death scene investigations commence without knowledge of the location of the body and/or decomposition site. In these cases, it is necessary to locate the remains or the site where the body decomposed prior to movement. We hypothesized that the burial of a mammalian cadaver will result in the release of ninhydrin reactive nitrogen (NRN) into associated soil and that this reaction might hav...
