Abstract
In this review we discuss the recent advances in the application of Raman scattering and related techniques to the detection of chemical and biological threat agents. One of the main aims of this review is to provide a new perspective on the application of advanced and emerging Raman techniques such as surface-enhanced Raman, spatially-offset Raman, waveguide-enhanced and coherent Raman spectroscopies, respectively, to the detection of threat agents such as explosives, toxins, viruses and bacteria. Combination with multivariate and computational analysis to augment the analytical abilities of Raman techniques as well as hyphenation and integration with various field deployment strategies such as robotic and stand-off detection are discussed. Importantly this interplay between the detection technique, analysis and engineering technology will be essential for developing powerful solutions for field applications in defence and security.
