Identification of Forensic Fabrics Using a Portable Raman Spectrometer

At a crime scene, a police officer collects a fiber sample that may prove to be invaluable evidence in identifying a criminal or exonerating an innocent person. In this study, we show how Raman spectroscopy, which has been studied extensively for forensic fiber analysis, is a perfect fit for this scenario because of the high selectivity of Raman signatures, non-destruction nature of the test, and the ability to conduct the analysis without any sample preparation.
