"Visualization of latent fingerprint deposits on metals by enhancing the fingerprint-induced corrosion is now an established technique. However, the corrosion mechanism itself is less well understood," scientists in the United Kingdom report (see also Forensic Science).
"Here, we describe the apparatus constructed to measure the spatial variation (Delta V) in applied potential (V) over the surface of brass disks corroded by latent fingerprint deposits. of Delta V for potential of 1400 V has enabled visualization of fingerprint ridges and characteristics in terms of this potential difference with Delta V typically of a few volts. This visualization is consistent ...
