What About Nanotechnology in the Developing World?

In the developing world, Brazil , Chile , China , India , the Philippines , South Korea , South Africa and Thailand have shown their commitment to nanotechnology by establishing government-funded programmes and research institutes. Researchers at the University of Toronto Joint Centre for Bioethics have classified these countries as 'front-runners' ( China , South Korea , India ) and 'middle ground' players ( Thailand , Philippines , South Africa , Brazil , Chile ). In addition, Argentina and Mexico are 'up and comers': although they have research groups studying nanotechnology, their governments have not yet organised dedicated funding.

Nanoscale Filters for Improved Water Purification Systems

Filters that are structured on the nanoscale offer the promise of better water purification systems that are cheap to manufacture, long-lasting and can be cleaned. Other similar technologies could absorb or neutralise toxic materials, such as arsenic, that poison the water table in many countries including India and Bangladesh .

What the ETC Group Says About Nanotechnology

Although some of these concerns, mainly the 'grey goo' theory, have been widely discredited by researchers in the field, most remain high on the agenda of activists. The ETC Group has demanded that a UN moratorium be placed on all nanotechnology applications that could come into contact with the human body. The ETC Group has also expressed concern that the control of nanotechnology research and development might remain firmly in the hands of industrialised nations. The result would be a bias towards developing applications that benefit rich countries but neglect the needs of the poor.
