In forensics, cyanoacrylate ester has excellent non-destructive impressioning abilities, which are especially important when lifting fingerprints from delicate evidence items, or when the prints could not be lifted using traditional means such as fingerprinting powder. The procedure involves heating the acrylate in a sealed chamber. Its fumes then react with deposited proteins that form into a white, stable, and clear print outlines. The resulting prints could be used as is or enhanced further by staining them with darker pigments.[4][5]
