Nanotechnology paves way for new weapons
Advances made in the field of nanotechnology could be applied in the development of a new generation of chemical and biological weapons, writes Andy Oppenheimer.
Current and future developments in nanotechnology—science and engineering on the scale of nanometres or billionths of a metre—may pave the way for new types of weapons. The new technology will have a profound impact on new materials, electronic devices, chemical, biological and mechanical systems and provides the potential for future weapons development. Previous articles on Janes Chem-Bio Web discussed the potential of nanotechnology being used for a fourth generation of nuclear weapons. This article deals with its potential to enable future production of novel chemical and biological weapons (CBW).
Dual-use medical advances
Nanotechnology has great potential in the fields of biotechnology and medicine. Bio-nanotechnology is concerned with molecular-scale properties and production of materials and devices including tissue and cellular engineering scaffolds, molecular motors and biomolecules for sensors and drug delivery. While bio-nanotechnological products are seen as around 10 years off, medical application is promising, with intense research being conducted in disease diagnosis, drug delivery and molecular imaging. Medical-related products containing nanoparticles are currently on the market in the US. DNA-based geometrical structures (including artificial crystals) and functioning DNA-based nanomachines are currently being fabricated.
