All the major countries are focusing on nanotechnology for use in their defense systems. Sweden has been running the Swedish Defence Nanotechnology Programme which is a dedicated program for research in the area of defense nanotechnology whereas other Asian and European countries have integrated their nanotechnology research in the existing defense programs.
The major investment is being undertaken by the U.S. Department of Defense which has allocated thirty percent of its funds towards nanotechnology research. The various areas where the major research is taking place is biological and chemical sensors, explosives, air and naval vehicles, structural material for ground and power generation and storage.
One of the U.S Army document states:
A key component of the leadership role in nanotechnology is protecting the work force, civilian and military, from the unintended consequences of nanotechnology processes and materials. The Army should take an active role in drafting environmental, safety, and occupational health guidelines for nanomaterials to ensure contractors follow best environmental practices in the development, manufacture, and application of the new technology.
