MVC®/D Applications

 

Cyanoacrylate or superglue fuming is a commonly used method of developing latent fingerprints on a wide variety of surfaces.

When cyanoacrylate glue evaporates it reacts with the amino acids, fatty acids, and proteins in the fingerprint and moisture in the air to produce a visible white material that forms along the ridges of the fingerprint. This can be photographed as is or further enhanced by dusting with a colored powder or by staining with a fluorescent dye.

Fingerprint fuming using PolyCyano UV, a compound of cyanoacrylate and a fluorescent dye, works in much the same way as detailed above, however, the material formed along the ridges of the fingerprint is immediately fluorescent under UV illumination and does not require a secondary treatment.

 

Cyanoacrylate examples:

A fingerprint on black tile under visible examination

A fingerprint on drinks can stained with Rhodamine 6G, green illumination with a 590nm filter

 

PolyCyano UV examples: 

A fingerprint on polystyrene under UV illumination

A fingerprint on white leather under UV illumination
