What is an alternative name for superglue in latent print development?

• A. Dimethyl Sulfoxide
• B. Cyanoacrylate
• C. Acrylic Resin
• D. Polyurethane

Answer: (B)

The correct answer is Cyanoacrylate, which is indeed an alternative name for superglue. In latent print development, cyanoacrylate vaporization is a widely utilized technique for revealing fingerprints. When cyanoacrylate is heated, it forms vapors that adhere to the moisture and lipids present in latent prints, resulting in a visible white coating on the ridges of the fingerprints. This method is particularly effective because it can be used on various non-porous surfaces, such as glass and plastic, that are common at crime scenes. The other options are not suitable alternatives for superglue in this context. Dimethyl Sulfoxide is a solvent often used in various chemical processes but does not play a role in fingerprint development. Acrylic Resin is more commonly associated with coatings and adhesives but is not utilized in latent print techniques in the same way. Polyurethane is a type of polymer used for various applications, including foams and coatings, but is not directly linked to the development of latent prints. Thus, the application of cyanoacrylate in forensic science specifically highlights its unique suitability for enhancing latent fingerprints.
