Chemical fingerprint

A fingerprint is more than just the pattern of lines that our fingers leave behind. The print also contains many biochemical substances: DNA, oils, amino acids. According to the Dutch Forensic Institute (NFI), these substances combine to form a chemical fingerprint that can also provide considerable information about a perpetrator at a crime scene. Researchers from the NFI will be collaborating with TU Delft researchers from the ChemE/Organic Materials and Interfaces research group (Applied Sciences) on a small device that can detect these materials at the scene.
