“…In general, Raman spectroscopy as a complementary method to the traditional ones offers the prospective to identify the main dye used for imparting the color of fibers. The approach of using different wavelengths may lead to the detection of additional dye components . The practice of dye identification is usually not conducted during forensic fiber examinations by means of the traditionally utilized methods.…”

In the second part of this survey, the ability of micro-Raman spectroscopy to discriminate 180 fiber samples of blue, black, and red cottons, wools, and acrylics was compared to that gathered with the traditional methods for the examination of textile fibers in a forensic context (including light microscopy methods, UV-vis microspectrophotometry and thin-layer chromatography). This study shows that the Raman technique plays a complementary and useful role to obtain further discriminations after the application of light microscopy methods and UV-vis microspectrophotometry and assure the nondestructive nature of the analytical sequence. These additional discriminations were observed despite the lower discriminating powers of Raman data considered individually, compared to those of light microscopy and UV-vis MSP. This study also confirms that an instrument equipped with several laser lines is necessary for an efficient use as applied to the examination of textile fibers in a forensic setting.

“…In 2012, the European Network of Forensic Science Institutes' European Fibres Group (EFG) published an important collaborative study showcasing the advantage of Raman spectroscopy's high sensitivity, as compared to light microscopy and MSP, through their analysis of fibers with varying dye concentrations . The EFG demonstrated that Raman spectroscopy was better suited to detect dyes in fibers at lower concentrations, specifically with reactive dye yellow 145 and reactive blue 221, which were detected at concentrations of 0.05% and 0.005%, respectively.…”

For decades Raman spectroscopy has been used as a specialized tool in a variety of fields. Forensic science is one discipline in particular that has greatly benefited from the application of Raman spectroscopic research. Here, studies using Raman spectroscopy for analyzing criminalistic evidence, including body fluids, human tissue, bones, gunshot residue, fibers, and hair, are reviewed. Many of these methods demonstrate the significance of incorporating chemometrics for data analysis to provide more reliable and quantitative results with associated errors. Currently, there are only a few branches of forensic science that use Raman spectroscopy in practice, despite its wide range of advantages. However, many more applications have been developed in the research setting and are presented here. These studies showcase the versatility and dependability of Raman spectroscopy, specifically for criminalistic purposes. The advantages of developing and transitioning these techniques to be used in practice are also discussed, including the tremendous benefits of portable instrumentation. Raman spectroscopy can easily become an established analytical technique for many criminalistics disciplines because it allows for obtaining real‐time, rapid, impartial, statistically confident results. Consequently, the improvements to forensic science as a whole will be revolutionary. Copyright © 2015 John Wiley & Sons, Ltd.

“…This characteristic has also been observed in the cases of the detection of dyes from textile fibers . However, it has been reported that changing the laser wavelength could occasionally lead to the detection of other dye components . Although the instrument used in this study also has an argon laser with a 532‐nm excitation wavelength, no data have been collected using this laser line to date.…”

Inkjet printers are ubiquitous devices in our society. Therefore, it is not surprising that they are used to commit different types of illicit activities such as threats or extortions by means of anonymous letters, frauds in the context of disputed contracts, alterations to or counterfeit of ID documents, or counterfeit of currency banknotes. This latter application is of primary interest in this study, where a method to rapidly develop investigative leads is required. Inkjet printed documents produce microscopic colored dots that can be detected using a microscopical approach in conjunction with Raman spectroscopy. The overall goal of this project is to investigate if Raman data gathered from the three cyan, magenta, and yellow microscopic colored dots constitute, in conjunction, a chemical signature of sufficient discriminating quality to provide reliable investigative leads in a time‐effective and nondestructive manner. In the present phase of this study, the criteria necessary to achieve discriminations between inkjet printer inks from different manufacturers, the same manufacturers, and even the same models have been evaluated on a set of 11 samples. Although Raman spectroscopy is already a relatively well‐established method for the characterization of colorants (both dyes and pigments), this study demonstrates that the contribution of minor peaks within Raman spectra improves the discriminating capabilities of the technique. The joint consideration of the three colored components was also effective in differentiating inkjet printer ink samples, especially those from the same manufacturer and in some instances from the same model as well.
