Research teams from the Alaska Scientific Crime Detection Laboratory and the 3M Company have worked independently to develop fingerprint development techniques using fluorescent cyanoacrylate techniques.
Abstract
The crime laboratory has developed a device the size of a pen that can develop cyanoacrylate fingerprints anywhere in about 20 seconds. A crime scene vapor pump has also been designed for use in large crime scenes such as entire residences. The research conducted by the two teams has focused on chemical synthesis and evaluation of four new cyanoacrylate adducts; application devices, using cured cyanoacrylate at high temperatures that are easily exported to field use at crime scenes; and a combination of both teams' research using a subliming dye tag and vapor want. The research also revealed that a co-volatization of a subliming 3M thermal material with cyanoacrylate succeeded in tagging fingerprints consistently on all types of surfaces. The 3M Company hopes to announce production and general availability in the third quarter of fiscal year 1993. Photographs and figures
