Electrochemical visualization of latent fingerprints using polyphenazine dyes on the brass cartridges

Original language description

The presented work is focused on the visualization of latent finger-prints left on brass unfired cartridges. Polymer films were preparedfrom 2 mM neutral red or 5 mM toluidine blue, respectively, using,alternatively, two different electrochemical methods (cyclic voltam-metry or chronoamperometry) with relatively short polymerizationtime. The conditions for depositing conductive polymers poly(neutralred) and poly(toluidine blue) from a neutral medium (phosphatebuffer with 0.1M KNO or 0.1 M KNO , respectively) were optimized to3 3preserve genetic information while producing high quality visuali-zation of fingerprints left on brass substrates. The surface mor-phology and quality of the polymer films after the electrochemicaldeposition of both polyphenazine dyes were characterized optically.Finally, a methodology is proposed, how to apply this technique ofvisualizing latent fingerprints with observed details of papillary linesin forensic practice.
