The use of cyanoacrylate fumes as a latent print development process for nonporous evidence items has been widely accepted by fingerprint laboratories throughout the world.
Abstract
Some laboratories use glue packets, while others use liquid adhesive with some sort of heating device. One method routinely used by the Immigration and Naturalization Service (INS) Forensic Document Laboratory involves placing liquid adhesive in an aluminum tray and gently heating the substance to accelerate volatilization. Those who use liquid glue methods may have encountered situations where the glue has dried in the bottle and become hard. Tests conducted at the INS laboratory, however, show that even dried cyanoacrylate will continue to develop latent prints in the same manner as liquid glue. The amount of solid adhesive required depends on container volume and evidence quantity being processed. 3 figures
