superglue fuming

Superglue fuming is a forensic technique used to visualize latent fingerprints on surfaces. When cyanoacrylate (superglue) vapor is heated in a sealed chamber, it releases fumes that adhere to the moisture and oils left by a fingerprint. These fumes harden into a white, visible deposit, revealing the fingerprint’s patterns. This method is particularly effective for non-porous surfaces like plastics or glass, allowing investigators to develop clear prints for identification. Superglue fuming is a safe, efficient process that enhances the visibility of evidence often invisible to the naked eye.
