Abstract

The spread of terrorist events over the globe in the last decade has emphasised the importance of detecting concealed explosives and led to calls for new advanced technologies to protect the public. Because most explosives release little vapour, it is not possible to detect them effectively by methods widely used on other chemicals. Detecting explosives is a very complex and costly task because of a number of factors, such as the wide variety of compounds that can be used as explosives, the vast number of deployment means, and the lack of inexpensive sensors providing high sensitiv‐ity and selectivity simultaneously. High sensitivity and selectivity, combined with the ability to lower the production and deployment costs of sensors, is essential in winning the battle on ex‐plosives‐based terrorism. Nanotechnology based sensors have strong potential for meeting all the requirements for an effective solution for the trace detection of explosives. This BRIEFING outlines the social and economical relevance of nano‐enabled technologies for the detection of explosives in security applications, provides background information on the technology, and highlights further chal‐lenges to be addressed.
