Characterization of electrochemically visualized latent fingerprints
Original language description
20th International Students Conference "Modern Analytical Chemistry", Prague: This work presents an electrochemical approach to the visualization of fingerprints on brass cartridges with the aim of characterizing how visualization using polyphenazine dyes affects latent fingerprints. Cyclic voltammetry and chronoamperometry have been used to deposit thin polymer films that visualize fingerprints. After visualization the individual layers substrate/fingerprint/polymer film and their interfaces were characterized profilometrically, spectroscopically (FTIR) and via SEM. With the help of SEM images, it was possible to assess the quality and morphology of the applied polymer layer. Profilometry showed the homogeneity and surface roughness of the deposited layers. Based on the FTIR spectra, it can be concluded that polymer films of dyes are deposited on the surface of the substrates due to the observed changes and band intensities belonging to the mono- and polymer form of neutral red and toluidine blue, respectively. The electrochemical visualization method proved to be usable, gentle and relatively fast.
