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 supportive evidence in forensic investigations.
In crime scene investigations, a single strand of hair can make a huge difference in the evolution of a case or trial. In most cases, forensic scientists must look for clues hidden in minuscule amounts of substances or materials found at crime scenes. If a fallen strand of hair with root cells attached is found, a DNA test can reveal the identity of
