The materials that show some level of organization of the domains at nano level in 1D, 2D or 3D aspect are considered to be nanostructured. Such materials find application in the advancement of many branches of science such as medicine, pharmacy, electrical engineering and military engineering. Generally, the development of the nanostructured materials inevitably brings about the development of the whole nanotechnology. For military applications, the goal is to make use of the nanostructured materials to reach advancement in equipment and techniques. For example, nanostructured materials based on nanotubes of various materials (carbon, titanate) are the basis of various sensors. Sensors based on nanostructured materials have proven parameters, surpassing those of conventional CBRN sensors in sensitivity and onset response. Thereof they are highly interesting to military, yet the difficulties to easily reach CBRN conditions has recently hindered greater extent of the mentioned investigations. Further investment in research of such sensors could allow better understanding of their functionality, support military CBRN defence and facilitate citizens' safety.
