Abstract

Raman spectroscopy was used to compare body fluids commonly found at crime scenes in a nondestructive manner. The dry traces of semen, vaginal fluid, sweat, saliva, and blood were analyzed using confocal Raman microscopy with a 785-nm excitation. The results show that the five fluids can be differentiated from one another by visual comparison of their Raman spectra, and that the laser radiation does not damage the sample. The Raman signature of each body fluid is specific and correlates with the known composition of the fluid. Dry traces of human and canine semen exhibited distinctly different Raman signatures. Overall, this preliminary study demonstrates the great potential of Raman spectroscopy for nondestructive, confirmatory identification of body fluids for forensic purposes.
