High fashion detective work. By Catriona Jenner Harvey.
Lipstick has many uses: it makes you look chic, adds color to an outfit, and — scientists have discovered — helps solve crimes.
In the same way as fingerprints are extracted from crime scenes and analyzed to provide clues about the perpetrator, experts are now discovering that they can do the same with lipstick.
Although attempts have already been made to extract lipstick from surfaces, they have involved 'X-ray refraction' or 'Raman spectroscopy' and have been hugely time consuming, confusing, and costly.
But now experts are using 'gas chromatography' to help the process, according to Medical Daily. Apparently this involves adding an organic solvent to extract the oils and waxes from the lipstick, and then adding a basic organic solvent to remove any of the remaining residue. While the scientists at Western Illinois University, who are researching the matter, are currently just lifting samples from paper, they hope to extend this to all sorts of materials and surfaces from a crime scene in the future.
So there's a lesson to be learned here, one and all: Don't wear lipstick when you're off to commit a massive crime because chances are you'll get a smudge of it somewhere, and the feds will be right on your tail.
Feels like there's a movie in there somewhere...
