Forensic Identification of Single Dyed Hair Strand Now Possible
Scientists develop modern analytical techniques as a tool for advancing forensic investigations December 10, 2020 A single strand of hair in a crime scene contains many clues that can help identify a perpetrator. In a recent study, scientists at Tokyo University of Science, Japan, have combined two modern techniques, called surface-enhanced Raman spectroscopy (SERS) and X-ray fluorescence (XRF), to distinguish between different colors in individual hair strands. Both these techniques are almost non-destructive and can be conducted with portable devices, making this a promising way to get supp...
