Nanotechnology refers to engineered structures, devices, and systems. In the "bottom-up" approach, materials and devices are built from molecular components which assemble themselves chemically by principles of molecular recognition. By post-9/11 operations in Iraq and Afghanistan, the aircraft most closely identified with UAVs by the public, media, and enemy was the Predator, which combined traditional intelligence, surveillance, and reconnaissance (ISR) capabilities with a Hellfire missile, turning it into the worlds first hunter/killer aerial robot. In that case, the terrorists were attempting to defend the world from "grey goo" by sending letter bombs to researchers they suspected of conducting nanotechnology research. 'Nanotechnology' is taken to include the ability to individually address . However, Drexler and other researchers[27] have proposed that advanced nanotechnology, although perhaps initially implemented by biomimetic means, ultimately could be based on mechanical engineering principles, namely, a manufacturing technology based on the mechanical functionality of these components (such as gears, bearings, motors, and structural members) that would enable programmable, positional assembly to atomic specification. [7] The associated research and applications are equally diverse, ranging from extensions of conventional device physics to completely new approaches based upon molecular self-assembly,[8] from developing new materials with dimensions on the nanoscale to direct control of matter on the atomic scale. The nanomaterials field includes subfields which develop or study materials having unique properties arising from their nanoscale dimensions.[35]. When the term "nanotechnology" was independently coined and popularized by Eric Drexler (who at the time was unaware of an earlier usage by Norio Taniguchi) it referred to a future manufacturing technology based on molecular machine systems. Such bottom-up approaches should be capable of producing devices in parallel and be much cheaper than top-down methods, but could potentially be overwhelmed as the size and complexity of the desired assembly increases.
