Super glue, also known as cyanoacrylate adhesive, is a powerful tool used by forensic investigators to lift fingerprints from various surfaces. This technique, known as cyanoacrylate fuming, involves exposing the surface with the fingerprint to super glue fumes, which then adhere to the oils and residues left behind by the fingerprint.
Super glue can be used to lift fingerprints from a wide range of surfaces, including glass, metal, plastic, and even paper. The adhesive nature of super glue allows it to bond with the residue left behind by the fingerprint, making it easier to lift and preserve the print for analysis.
One of the key benefits of using super glue to lift fingerprints is that it can be used on both porous and non-porous surfaces. This versatility makes it an invaluable tool for forensic investigators, as they can use it on a variety of surfaces to collect evidence and solve crimes.
In addition to its effectiveness in lifting fingerprints, super glue is also relatively easy to use. Investigators simply need to place a small amount of super glue in a container, heat it to release the fumes, and then expose the surface with the fingerprint to the fumes. After a few hours of exposure, the fingerprint should be visible and ready to be lifted using tape or a special lifting tool.
Overall, super glue is a valuable tool for forensic investigators when it comes to lifting fingerprints from a variety of surfaces. Its adhesive nature, versatility, and ease of use make it an essential part of any forensic toolkit. So, whether you're investigating a crime scene or analyzing evidence in a lab, super glue can help you lift and preserve fingerprints for further analysis.
