Scientist Using Microscope

In forensic science, Raman spectroscopy analysis is a rapid tool for non-destructive identification of trace evidence such as drugs, explosives, inks, and fibers. It allows forensic experts to analyze samples directly at the crime scene using portable Raman devices. This technique is highly effective for identifying unknown substances without altering the evidence. Raman spectroscopy is also used to examine gunshot residues, body fluids, and paints in criminal investigations. Its precision and ability to work with minute samples make it a powerful tool in modern forensic analysis.

 Raman Spectroscopy Analysis in Forensic Science

Petri Dishes with Experiment

Raman Analysis Biological samples

  • Raman spectroscopy allows non-destructive chemical and molecular profiling of forensic samples like fingerprints, blood, semen, bones, skin, and nail polish.

  • It overcomes limitations of destructive methods (like luminol or tape-stripping) while preserving evidence.

  • Provides rapid, comprehensive, and reliable analysis, improving accuracy in crime investigations.

Movie Set Explosion

Raman Analysis  in Detection of the explosives and residues

  • Raman spectroscopy is a key tool for identifying explosive compositions even from minimal residue samples after terror attacks or blasts.

  • It enables non-invasive, on-spot detection of chemicals like ammonium nitrate and its degradation products.

  • Safer and more specific than traditional methods, it helps trace explosive residues in suspected areas

White Powder

Raman Spectroscopy in illegal Drug Identification

  • Use of Handheld Raman spectroscopy for on-spot, non-invasive identification of the drugs and their composition directly through the packaging at crime scenes.

  • Difficulty in determining the adulterants like caffeine mixed with drugs leads to health risk and complications

  • Conventional methods like colorimetric testing are cheap but prone to false positives

Crime Scene Investigator

Raman Analysis in Trace Evidence and Material Identification

  • Even tiny materials like textile fibers can provide crucial crime insights; Raman spectroscopy reveals fiber material and dye composition more effectively than IR.

  • It can help establish links between victim and suspect, aiding in cases of kidnapping, assault, or suspected murder.

  • In forgery detection, Raman spectroscopy identifies different ink compositions and, with confocal analysis, detects document tampering or counterfeit currency

Drought

Raman Analysis in Post-mortem Interval (PMI) Estimation

  • Estimating post-mortem interval (PMI) from skeletal remains is difficult, and existing methods are destructive or hazardous.

  • Raman spectroscopy analyses mineral and organic components of bone to study degradation and estimate time of death.

  • It also helps distinguish between forensic remains and archaeological samples, adding accuracy to investigations
