Cyanoacrylate super glue reacts with the traces of amino acids, fatty acids, and proteins in the latent fingerprint and the moisture in the air to produce a visible, white polycyanoacrylate that forms along the ridges of the fingerprint. Super Glue Fuming is suitable for use on: Cardboard. Fingerprints leave Submit every item you superglue fume to the lab, whether or not you see anything on it. As long as your test print came out okay, the lab has a good chance of enhancing invisible latent prints you have developed on the evidence. When used with common sense, superglue fuming is a very safe technique used by police worldwide daily. DO NOT USE A HOT PLATE. The superglue fumes react with the amino acids on the latent prints, and cause them to become visible. The process of fingerprint fuming is relatively easy. Superglues should not be applied to critical joints that are expected to experience significant shear stress. True False. A key problem with DIY field methods, however, is a lack of repeatability and an inconsistency in results.
