The detection and/or identification of trace amounts of explosives. The review of each method should include a description of the way the method works and the advantages and drawbacks of the technique. Introduction An explosive, are reactive substances that contain a large amount of potential energy that can yield an explosion if they are released rapidly, they are accompanied by the production of light, heat, sound, and pressure. Mainly used in the mining industry for extraction of minerals and resources, explosives have been used as a weapon of destruction. Explosives often contain oxidising substances such as nitrates chlorates, and a binding agent such as ammonium and potassium, which can be detected and analysed to prevent such substances from being used as a weapon. Explosives detection is critically important in many field settings (e.g., military facilities, minefields, crime scenes, and remediation sites) and has become a necessity for the safety of the general public (e.g., at airports and mass transit areas), there remains a demand for inexpensive and reliable explosive instruments for identifying specific explosives. High explosives are considered to be organic and oxidizing, a relatively uncommon mixture that makes them tractable for molecular recognition. On 22 December 2001 Richard Colvin Reid also known as the Shoe Bomber attempted to detonate explosives packed into the shoes he was wearing, while on American Airlines Flight 63 from Paris to Miami.
