Should superglue fuming be done at the scene of the crime or back at the lab? PDF Cyanoacrylate fuming method for detection of latent fingermarks: a review 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.
