ABSTRACT
context: Detection of explosives is indeed crucial for the fact that it has a harsh impact upon peace in the community as well as its nature as a contaminant in the environment. As of now, there have been numerous additions due to clandestine synthesis of explosive materials which are not up to date with the spectral library of various spectrometric techniques. For the detection of explosives, new mechanisms are often required which should have advantages like sensitivity, selectivity, rapid response, low cost, remote sensing and sensors made with ecofriendly material. Techniques which are commonly utilized areIon Mobility spectrometry, Gas Chromatography – Mass Spectrometry, Fido-XT for sensing explosives like Trinitrotoluene (TNT), Trinitrophenol (TNP), and Dinitrotoluene (DNT) etc. Apart from that, military agencies, police and forensics are still having a hard time to detect the trace amount of explosives like RDX, PETN, Tetryl and HMX etc. selectively. Recent upbringing in Chemiluminescence based explosive detection showed quite a reliable way for detecting these compounds. In Chemiluminescence based detection various materials are used namely conjugated fluorescent polymers, small molecule fluorophores, supramolecular system, Bio-inspired fluorescent materials, Aggregation induced emission active materials. These techniques if combined with various techniques like electronics, imaging and sensor design then it would provide deployment over real field for explosive detection which includes buried land mines, environmental contamination by explosive material. This review article may help the readers in order to get insight about what is explosive, various types of explosive, and mechanism of explosion and explosive detection techniques.
