Detecting latent fingerprints. A technician uses a blue light to detect latent fingerprints on objects from a crime scene. The items have been subjected to Lumicyano cyanoacrylate fuming in a heated cabinet. Cyanoacrylate is warmed to produce fumes that react with the invisible fingerprint residues to form a fluorescent polymer on the fingerprint ridges,which glows under blue light. This method is non-destructive,allowing any DNA in the fingerprints to remain intact | |
