“…The combination of various methods is an effective way to ensure accurate detection. By sharing lasers, spectrometers, and optical paths, a combination of different spectral methods (such as Raman and LIBS) can be implemented in a single instrument, and various efforts are required to reduce the size and complexity of the instrument [ 134 , 135 ]. In addition, new analytical methods need to be developed to detect explosives faster and more sensitively.…”

Trace detection of explosives has been an ongoing challenge for decades and has become one of several critical problems in defense science; public safety; and global counter-terrorism. As a result, there is a growing interest in employing a wide variety of approaches to detect trace explosive residues. Spectroscopy-based techniques play an irreplaceable role for the detection of energetic substances due to the advantages of rapid, automatic, and non-contact. The present work provides a comprehensive review of the advances made over the past few years in the fields of the applications of terahertz (THz) spectroscopy; laser-induced breakdown spectroscopy (LIBS), Raman spectroscopy; and ion mobility spectrometry (IMS) for trace explosives detection. Furthermore, the advantages and limitations of various spectroscopy-based detection techniques are summarized. Finally, the future development for the detection of explosives is discussed.

“…The Raman cross sections used for this analysis are the average values of the solution and solid measurements (where available) published in references. [61][62][63] For a 100 nm thick sample, the attenuation even at 229 nm is small, and the relative Raman signal closely follows the Raman cross section. However, a sample thickness or particle diameter this small is not likely to be encountered operationally.…”

In 2010, the U.S. Army initiated a program through the Edgewood Chemical Biological Center to identify viable spectroscopic signatures of explosives and initiate environmental persistence, fate, and transport studies for trace residues. These studies were ultimately designed to integrate these signatures into algorithms and experimentally evaluate sensor performance for explosives and precursor materials in existing chemical point and standoff detection systems. Accurate and validated optical cross sections and signatures are critical in benchmarking spectroscopic-based sensors. This program has provided important information for the scientists and engineers currently developing trace-detection solutions to the homemade explosive problem. With this information, the sensitivity of spectroscopic methods for explosives detection can now be quantitatively evaluated before the sensor is deployed and tested.
