Gas Nano sensors for Detection of Explosives

Detecting explosives is a challenging task because of a number of factors, such as the low vapor pressures of most explosives, frequent introduction of novel explosive compositions, concealment and weapon delivery schemes. Also, selective and sensitive detection of explosive has received considerable attention for environmental monitoring/ restoration and national security applications. Nano sensors with increased sensitivity and selectivity and the ability to operate in a multimodal platform offer a potential paradigm for deploying a large number of sensors for detection. This review is intended to highlight recent advances in vapor detection of explosives by enabled nanotechnology sensors.
