Police use various methods to detect fingerprints, primarily relying on powders, chemicals, and digital scanning technologies. Fingerprint powders, often made from carbon or aluminum, adhere to the oils and sweat left on surfaces, making the prints visible. Chemicals like ninhydrin and cyanoacrylate (super glue) can also be used to reveal latent prints on porous and non-porous surfaces, respectively. Once identified, prints are often captured digitally for analysis and comparison against databases.

Additionally, fingerprints can regenerate over time, making long-term alteration challenging.
Why did John Bond try to create enhanced fingerprints?
John Bond and his team at the University of Leicester attempted to create enhanced fingerprints for forensic identification purposes. The goal was to improve the visibility of latent fingerprints on various surfaces, making them easier to detect and analyze. Enhanced fingerprints could potentially provide better evidence in solving crimes and aid in criminal investigations.
