Nano and Advanced Sensing Techniques for Combating Chemical, Biological and Explosive Threats
Published: October 21, 2014 Content info: 74 Pages
Description

In recent years, in the quest for ensuring the safety of populations against the potential use by terrorists of a wide range of chemical, biological and explosive threats has underlined the need for early, sensitive and reliable detection. This has led to research on new advanced sensing technologies that can offer protection of life and property.

Nanotechnology has the potential to satisfy all the requirements for an effective platform for the trace detection of many, if not all, of chemical, biological and explosive-based threats. The high sensitivity and selectivity of nanosensors can be utilised in detecting for example, biological threats like anthrax, plague, smallpox etc. They can also be used for detecting explosives and in the detection of toxic gas agents such as sarin.

In this report, over 30 technologies that can be deployed in sensing, and their wide-ranging applications, are described. For each technology, abstracts of relevant papers explaining their utilisation, patents, press releases and reviews are included, along with links to further information.
