Chemical studies into the amino acids present in latent fingermarks
MetadataShow full item record
The aim of this research was to carry out investigations into the amino acid chemistry of latent fingermarks. Amino acids are the primary targets of chemical visualisation methods for fingermarks deposited on porous substrates. Two novel amino acid sensitive reagents for the detection of latent fingermarks were formulated and evaluated. Analytical chemistry methodology was developed and subsequently applied to examine the amino acid content of latent fingermarks deposited on paper.
