Superglue primarily reacts with which component in the latent print deposit?

Superglue primarily reacts with water present in the latent print deposit. When superglue, or cyanoacrylate, is used in the process of fuming, the moisture found in the latent print facilitates a chemical reaction that causes the superglue to polymerize. This reaction forms a solid, visible imprint that can be analyzed for fingerprint identification.

The latent print deposit itself commonly consists of various constituents like oils, fats, and other substances, but the reaction of superglue is specifically reliant on the moisture level of the print residue. By reacting with water, superglue adheres to the print, allowing the fine details of the fingerprints to be made visible, which is crucial in forensic analysis.
