ABSTRACT
Security is the key factor of world's peace. Terrorists are using Improvised Explosive Devices (IED) for their attacks. Identification of IED is not simple, the only way to identify IED is by using chemical sensors but using a chemo sensors is quiet complex and more expensive. So we brought nano sensors to identify it. Using nano sensors is much efficient & highly sensitive at the single molecule level. Nano materials provide a strong potential to create sensors for detecting explosives. Electronic noses, nano wire / nano tube and nano material device are nano sensor concepts with strongest potential to form detecting devices & also to detect the conventional bombs, plastic explosives and grenades. Generally IED can be identified by trained dogs but it is quiet difficult to maintain and using in sensational places. Electronic nose is mainly composed of chemical sensor system, sampling system and a pattern recognition system as a neural network. This composited detector can sense the odour difference caused by explosives and converts it to signals. For instance electrical conductivity in a nanotube changes due to interacting with molecules of an explosive analyze, as a result of highly selective adsorption. Nanomechanical effects induced by molecular adsorption offer unprecedented opportunities for trace explosive detection. Though nano is also implied in some screening techonologies, really developed sensors are nanosensors as it have advanced sensitivity and selectivity of explosive detection systems. There are some challenges in detecting explosives such as fabrication of sensors, providing stability, sampling and reliable calibration and identification of pattern in complex changing backgrounds. Overcoming the difficulties nano sensors combined with advances in conventional detection platforms have high efficiency and stability to detect by advanced solution concluded in the paper. All governments of world have now realized the significance of explosive threats.
