Depending on the laws of individual jurisdictions, forensic examination is the collection of evidence for review and use in legal proceedings. In a crime scene, a single strand of hair provides several clues that can aid in the identification of the suspect. In a recent research, scientists merged two modern techniques to differentiate between different colours in individual hair strands: surface-enhanced Raman spectroscopy and X-ray fluorescence. Both of these methods are virtually non-destructive and can be carried out with portable devices, making them a promising method of collecting supporting evidence in forensic investigations. A single strand of hair can make a significant difference in the result of a case or trial in crime scene investigations. In most cases, forensic scientists must scan small quantities of liquids or objects found at crime scenes for clues. A DNA test will expose the identity of a suspect if a dropped strand of hair with root cells is found; sadly, this rarely occurs. Despite the fact that other forms of DNA analysis may be performed using the "mitochondrial DNA" contained in the hair shaft itself, such tests are rarely enough to accurately identify an individual and usually necessitate the use of additional evidence. Raman spectroscopy is an analytical technique that models those energetic interactions that occur when photons interfere with matter and is based on the physical phenomenon of Raman scattering. SERS is a type of Raman spectroscopy that can show a material's "structural fingerprint" even when there are just a few molecules in the target sample. XRF research, on the other hand, entails irradiating a specimen with X-rays and measuring the energies of photons re-emitted as the sample's electrons exit their excited states. XRF analysis is particularly useful for determining the existence of metallic elements in a substance. The researchers used portable devices to perform SERS and XRF tests to see whether they could differentiate between single strands of hog hair dyed with different materials. SERS can easily differentiate between various types of hair dyes, such as permanent, semi-permanent, and natural dyes, based on their overall composition.
