You’ve probably heard of turmeric, a gold-colored spice used in Indian cuisine. What you might not know is that turmeric can be used to highlight and identify fingerprints as well as traces of drug abuse and other identifying characteristics of a suspect.
Criminal Justice Online is reporting that this new fingerprint technology using an old spice was developed by researchers at Sheffield Hallam University’s Biomedical Research Centre. The procedure is simple: dust with turmeric, lift, and send to mass spectrometry researchers to check for drugs, fatty acids, and other molecules on the print.
The findings are then passed on to forensic investigators. It’s an old-new way to find and enhance fingerprint evidence.
Now that little fun fact could be useful.
