“…Tetryl [28], PETN [29][30][31], EGDN [29,30], and KNO3 [31]. The LOD achieved for TNT was calculated to be 200 pg within the laser spot which came from 0.1 mL of 1 mg/mL TNT solution [27][28][29]. In subsequent studies, LOD for TNT was improved up to 20 pg This fact demonstrated that the precipitation of the explosive is not uniform.…”

Surface Enhanced Raman Scattering (SERS) has undergone an important development over the last few years, particularly in the detection and identification of extremely low traces of explosives. The large number of studies and results generated by this increasing research makes a comprehensive overview necessary. This work reviews in detail that research focused on the identification of explosives by SERS, including TNT, DNT, RDX, PETN, TATP, HMTD, perchlorate, etc. either in bulk state, in solution or in vapour phase. In brief, TNT and DNT have been widely studied by SERS due to its aromatic structure and LODs down to 5-10 zg and 10 -17 -10 -13 M have been achieved. The other explosives have been quite less researched; therefore, few results are available to be compared and a bit more modest LODs have been reached such as 10 -13 M for RDX, 10 -4 M for TATP, 5 pg for PETN, or 10 -9 M for perchlorate. In addition, the challenges of detecting both explosives vapours and perchlorate anion by SERS are thoroughly discussed.

“…343 Differences observed in vacancy formation and healing lifetimes of these materials could help guide development of PIERS substrates. Given the UV pre-irradiation step is sample-independent and the proven versatility of SERS in detecting a range of organic and inorganic explosives, [344][345][346] development of a reusable multi-target sensor is a possibility and would greatly benefit routine screening in civilian and military environments. These studies indicate potential further applications of established metal oxide SERS materials as PIERS substrates.…”

Explosive trace detection (ETD) technologies play a vital role in maintaining national security. ETD remains an active research area with many analytical techniques in operational use. This review details the latest advances in animal olfactory, ion mobility spectrometry (IMS), Raman and colorimetric detection methods. Developments in optical, biological, electrochemical, mass and thermal sensors are also covered in addition to the use of nanomaterials technology. Commercially available systems are presented as examples of current detection capabilities and as benchmarks for improvement. Attention is also drawn to recent collaborative projects involving government, academia and industry, to highlight the emergence of multimodal screening approaches and applications. The objective of the review is to provide a comprehensive overview of ETD by; highlighting challenges in ETD and providing an understanding of the principles, advantages and limitations of each technology and relating this to current systems.
