“…From the research on optical detection of IEs from 2010 to 2021 ( Figure ), it can be found that the detection limits of hypochlorite, [ 41–57 ] perchlorate, [ 58–60 ] peroxide, [ 61–77 ] nitrate, [ 78–85 ] and nitrite [ 86–99 ] based on solution reaction are mostly between 10 −5 and 10 −9 M , and it is difficult to achieve higher sensitivity detection by merely optical probes designing. By combining the sensing probes with paper‐based [ 19,100–103 ] and hydrogel‐based [ 28,104–106 ] substrate and optical microscope device, the detection sensitivity has been greatly improved in 2020 and 2021 reaching a level of 10 −15 M. To better improve the detecting sensitivity, optical artificial olfactory system takes chemical sensor array as the detection modules of different IEs, as well as considering the automatic analyte collection with airflow and the ultrasensitive ecognition of optical signals has been explored from the design of different components.…”

“…Gökdere et al, reported on the development of a paper and solid-based colorimetric sensor for TATP using functionalized titanium dioxide (TiO2) NPs [75]. For the construction of the TATP paper-based colorimetric sensor, the surface of TiO2 was first functionalized with (3aminopropyl)triethoxysilane (APTES) to form an APTES-coated-TiO2 NPs.…”

Warfare threats and acts of terror are challenging situations encountered by defense agencies across the globe and are of growing concern to the general public, and security-minded policy makers. Detecting ultra-low quantities of explosive compounds in remote locations or under harsh conditions for anti-terror purposes as well as the environmental monitoring of residual or discarded explosives in soil, remains a major challenge. The use of metal nanoparticles (NPs) for trace explosive detection has drawn considerable interest in recent years. For nano-based explosive sensor devices to meet real-life operational demands, analytical parameters such as, long-shelf life, stability under harsh conditions, ease-of-use, high sensitivity, excellent selectivity, and rapid signal response must be met. Generally, the analytical performance of colorimetric-based nanosensor systems is strongly dependent on the surface properties of the nanomaterial used in the colorimetric assay. The size and shape properties of metal NPs, surface functionalisation efficiency, and assay fabrication methods, are factors that influence the efficacy of colorimetric explosive nanosensor systems. This review reports on the design and analytical performances of colorimetric explosive sensor systems using metal NPs as optical signal transducers. The challenges of trace explosive detection, advances in metal NP colorimetric explosive design, limitations of each methods, and possible strategies to mitigate the problems are discussed.

“…At present, commercial explosive detection methods include riot dogs, [ 4 ] ion mobility spectrometry, [ 5–7 ] metal detectors, [ 8 ] Raman methods, [ 9 ] fluorescence methods, [ 7,10,11 ] and colorimetric methods. [ 12,13 ] Among them, there are riot dogs, ion mobility spectra, fluorescence methods, and Raman methods that can accurately identify the explosive. However, the above methods still have deficiencies.…”

The development of sensitive materials for standard and improvised explosives is greatly significant to homeland security. In this paper, the phosphotungstate (NaPT) doped polyphenylene vinylene (PPV) nanotube arrays (NTAs), with excellent optical response, chemical stability, and larger specific surface area, are successfully fabricated by means of the “precursor film” infiltration method. The efficient charge carriers' separation of PPV NTAs can be achieved by doping NaPT to realize the photoelectric detection of explosive vapors. In addition, the identification of six explosives, including ammonium nitrate (AN), dinitrotoluence (DNT), picric acid (PA), p‐nitrotoluene (PNT), triacetone triperoxide (TATP), and trinitrotoluene (TNT), can also be realized through the fingerprint atlas. Moreover, the adsorption energy and excited oscillator intensity has also been employed to explain the interaction between NaPT doped PPV nanotube arrays and various explosive molecules. Obviously, the NaPT doped PPV developed has the potential to be used as an explosive sensor.
