Nano weapons are any military innovation that adventures the quality of nanotechnology in the advanced front line. Nanotechnology has changed the present law, with the explicit spotlight on its capacity to deliver more prominent modern, scaled-down and custom-made weapons. Higher quality, quality thickness and intentional thickness would significantlyimprove the structures of current weapons. Smaller, ground-breaking bombs that utilisenano metals, for example, nano aluminium to make ultra-high consume rate substance explosives a request of greatness more noteworthy ground-breaking than customary bombs. Such an addition will increment the proficiency of assembling the final product, improve costs and thus substantially reduce the cost of weapons.
