Forensic analysis of fingerprint traces may benefit from a method for depositing thin films that conform to and thereby highlight the microscopic morphology of fingerprint residue (J. Vac. Sci. Technol. B 2014, DOI: 10.1116/1.4867440). The technique, which can be carried out with common deposition equipment, may help convert faint and hard-to-analyze prints to usable legal evidence. Fingerprint residues (or latent . . .
