Indian scientists have developed a thermally stable and cost-effective electronic polymer-based sensor for rapidly detecting nitro-aromatic chemicals used in high-energy explosives.
The detection of explosives without destroying them is essential for protection, and criminal investigations, minefield remediation, military applications, ammunition remediation sites, security applications. Chemical sensors play a vital role in such cases.
Though explosive poly-nitroaromatic compounds can usually be analysed by sophisticated instrumental techniques, the requirement for quick decision-making in criminology laboratories, reclaimed military sites or to detect explosives in possession of extremists often require simple and cheap field techniques which are non-destructive in nature.
