Fluorescence Spectroscopy for Forensics

Uncovering definitive, objective evidence from minute, complex samples requires analytical tools that maximize detection sensitivity without compromising the physical clue. Fluorescence spectroscopy serves as a premier, highly targeted solution in forensic investigations, exploiting the natural or chemically induced luminescent properties of trace materials. While standard imaging can miss hidden data, advanced fluorescence systems isolate latent fingerprints, illuminate faint biological fluid stains, and differentiate look-alike fibers, glasses, or gunshot residues based on unique molecular emission signatures. This non-destructive, high-contrast capability makes fluorescence indispensable across a spectrum of investigations, from exposing counterfeit documentation and fraudulent pharmaceuticals to tracking industrial contaminants and intentional product tampering. By delivering rapid, part-per-billion sensitivity and unmistakable spectral data, HORIBA’s fluorescence instrumentation empowers forensic labs to establish indisputable evidence, ensure regulatory compliance, and support the justice system with absolute confidence.

Why use fluorescence in FORENSICS 

  • SENSITIVITY
    Fluorescence markers are used because they are highly sensitive and specific 
  • SECURITY
    Unique fluorescence markers can be safely added to materials for anti-counterfeiting (currency, packaging, petroleum) 

 

What techniques are used to measure FORENSICS with fluorescence 

  • Upconversion 
  • Spectral analysis 
  • Fluorescence and phosphorescence lifetimes 
  • Fluorescence microscopy
