| BackgroundIn the USA, which can boast the most  government financial support for nanotechnology research in the world, nanotechnology  funding given by the federal government to the Department of Defense is  second only to that given to the National Nanotechnology Initiative (NNI). The  Massachusetts Institute of Technology (MIT) hosts the US Army Institute of  Soldier Nanotechnologies (ISN), a research unit devoted to developing  military applications for nanotechnology, its aim being to improve the  “survival of the soldier of the future”. Using  Smart Materials to Improve Body Armour The  Institute’s ultimate goal is to “create a 21st century battlesuit”. To this  end they are investigating smart materials able to be responsive to the  conditions of their environment, sensors able to detect chemical or  biological warfare agents, and lightweight bullet-proof materials. There are  also attempts to incorporate wound detection and treatment systems within  uniforms. For example, responsive systems, such as the material hardening to  provide an instant splint for a broken bone, are in development. The  five-year contract awarded in 2002 to MIT by the US Army implies the  time-scale for the development of these projects is rather near term. Lighter  and stronger weapons and equipment are being developed, although information  on this area is scarce and it is assumed that much of this research is classified.   Using  Nanotechnology to Improve the Human-Machine InterfaceIn  addition there is a focus on improving the human-machine interface, perhaps  including sensory enhancement such as direct retinal displays or  communication to the ear. Should these products be developed, and be able to  be manufactured, it is likely that they will be transferred to the space  programme and eventually into wider usage.  Using  Improved Materials in the Building of Spaceships Improved  materials, lighter but with tough, heat resistant properties, are being used  in the design and construction of spacecraft and satellites, and this process  will gain from nanotechnology. (Confusingly, the term nanosatellite is in use  but refers to a small satellite, not one using nanotechnology.)  Improving  Security Using Nano-Based Sensors, Nanoparticles and DNA NanotechnologyThere  is also the possibility of nanotechnology facilitating improvements in  civilian security equipment. The Institute of Nanotechnology suggests fingerprinting will  become cheaper, quicker and more effective using DNA techniques involving  nanotechnology, and there is also the possibility that nano-based sensors  could be used as electronic detectors (‘sniffer dogs’) for improved airport  security. Quantum dots, fluorescent nanoparticles which glow when exposed to  ultraviolet light, may be used as tags and labels to prevent theft and  counterfeiting, and to trace the course of drugs within the body. |
