How to Lift Fingerprints: Cyanoacrylate Super Glue Fuming
This video explains the science behind the cyanoacrylate fuming process and how it is used for latent fingermark detection. Cyanoacrylate superglue 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 poly cyanoacrylate that forms along the ridges of the fingerprint. This reaction takes place faster when the cyanoacrylate is heated inside a chamber with some water inside to provide humidity. Fingerprint powders can potentially contaminate the evidence and ruin the opportunity to perform other techniques that could turn up a hidden print or additional information. Therefore, investigators may examine the area with an alternate light source or perform cyanoacrylate (superglue) fuming before using powders.

Latent prints are not readily visible to the naked eye and must be developed in some way to increase their visibility and contrast. The method shown in this video is to physically enhance the latent prints by using a homemade cyanoacrylate fuming chamber. The fuming chamber can be made fairly easily or be substituted with a glass aquarium or clear plastic container.
