The visualization of latent fingerprints on metal surfaces using the electrochemical deposition of a polymer film based on poly(phenazine) dyes and poly(3,4 ethylenedioxythiophene), shortly PEDOT, is presented here. The experiment involved optimizing the conditions for the electrochemical deposition of dyes on brass and steel surfaces, and identifying characteristic details in the visualized fingerprints on different substrates (plates, coins and cartridges). When optimal conditions are achieved for cyclic voltammetry and chronoamperometry methods dactyloscopic traces are visualized with very good quality. The visualized fingerprints were recorded using optical microscopy. Experimental findings have shown that the electrochemical deposition of polymeric films may have an alternative possibility of use in dactyloscopy and on real objects (coins and cartridge cases), and at the same time this method offers a new approach to the visualization of dactyloscopic traces.
