Cutting-Edge Raman Spectroscopy Applied for Forensic and Heritage Studies

A recent compilation in the Journal of Raman Spectroscopy explores cutting-edge Raman spectroscopy techniques and their impactful applications in forensic science and cultural heritage preservation (1). The advancements include mobile systems, improved optics, and advanced data processing methods, pushing the boundaries of these fields.

Handheld X-Ray Technology Unveils New Forensic Tool

Researchers at the University of Porto have shown that handheld X-ray fluorescence spectrometers can analyze cigarette ash, offering a novel forensic investigation method. This non-destructive technique distinguishes between different tobacco brands by analyzing the elemental composition of their ash (2).

Determining the Age of Bloodstains at Crime Scenes Using ATR FT-IR Spectroscopy and Chemometrics

A recent study by Antonio Ortiz and María Dolores Pérez-Cárceles from the University of Murcia demonstrates that attenuated total reflectance Fourier transform infrared (ATR FT-IR) spectroscopy combined with chemometrics can accurately estimate the age of bloodstains at crime scenes (3). This technique provides a valuable tool for forensic investigations by helping to determine the time since blood deposition.

Compact LIBS Sensor Modernizes Crime Scene Forensics

Researchers have developed a portable LIBS sensor for crime scene investigations, capable of functioning in both handheld and tabletop modes (4). This device allows rapid, on-site analysis of forensic samples with enhanced sensitivity, offering a transformative tool for forensic science (4).

SEM/EDX Analysis on Suspected Cigarette Burns in a Forensic Autopsy Case of Child Abuse

A scanning electron microscopy/energy-dispersive x-ray (SEM/EDX) analysis of cigarette burns on a child's body provided crucial evidence in a forensic investigation. This analysis helped add child abuse charges against the alleged perpetrator (5).

The Scene of the Crime: Using NIR and UV-Vis Spectroscopy in Bloodstain Dating

A recent study investigates the use of near-infrared (NIR) and ultraviolet-visible (UV-vis) spectroscopy for determining the time since deposition (TSD) of bloodstains, a crucial factor in forensic investigations (6). By comparing these techniques, researchers seek to enhance the accuracy of bloodstain dating, offering valuable insights for practical forensic applications.
