Latent Fingerprints on the Neck of a Glass Bottle

Cyanoacrylate: Investigators often perform cyanoacrylate (superglue) processing, or fuming, of a surface before applying powders or dye stains.

This process, typically performed on non-porous surfaces, involves exposing the object to cyanoacrylate vapors.

The vapors (fumes) will adhere to any prints present on the object allowing them to be viewed with oblique ambient light or a white light source.
