Abstract

Several recent discoveries demonstrate that Raman spectroscopy has a unique capability to characterize body fluid traces in a forensic capacity. This approach has thus garnered interest in the forensic community since 2008, when a proof of concept experiment established that blood, semen, vaginal fluid, sweat and saliva are easily differentiable through their Raman spectra. Several possible methods of identification have been described in the literature, one approach uses chemometrical models, and another applies recently formulated multidimensional Raman signatures. The analytical sampling method and the identification procedure provide several desirable traits for the field of forensic science. In particular, Raman spectroscopy is non-destructive and has the potential to be rapid and field applicable.
