This opinion article argues that excessive concern about the risks of nanotechnology in developing countries could derail its progress and hinder the enormous health, environment and economic benefits to be gained from nanotechnology research. The authors identify the developing countries making the most advances in nanotechnology, those in the middle ground, and the "up and comers".

This report from PLoS Medicine argues that nanotechnology has a role in the development of low-income countries. The authors survey 85 experts worldwide and rank the top ten nanotech applications most likely to benefit developing nations. They outline how these applications can help meet the Millennium Development Goals. The paper calls for an initiative to identify "grand challenges" in nanotechnology for global health, which since the publication of this paper are now underway.

This follow-up paper, from the Journal of Nanotechnology Online, provides an in-depth look at the way poor countries engage with nanotechnology. It analyses why some developing nations are ahead of others in nanotechnology progress, and the challenges some less-developed countries face in shoring up nanotechnology capacity. It also investigates nanotechnology patent activity and assesses country participation in nanotechnology policy dialogues – for instance, China is a frontrunner in filing nanotech patents yet it is absent from policy discussions.

This essay by Chunli Bai, executive vice president of the Chinese Academy of Sciences (CAS), explains the reasons behind the rapid progress of nanotechnology in China. A key factor, says Bai, has been "extraordinary" government support for the field since the early 1980s, which led to the creation of research institutes and significant grant money. But, cautions Bai, public communication on nanotechnology research, and ongoing monitoring and assessment of nanotechnology risks is needed.

This report, published by the Meridian Institute describes the growing interest of developing countries including Brazil, China, India and South Africa, in nanotechnology. The ways nanotechnology applications could solve health, sanitation, and pollution problems and provide faster, cheaper information and communication technology are outlined. The challenges of using and developing nanotechnology for and in developing nations including the roles and responsibilities of different stakeholders are also discussed.

The Meridian Institute says nanotechnology can play a role in achieving the UN Millennium Development Goals. As a result, rich nations should dedicate a reasonable portion of their overseas development assistance to nanotechnology.

Mohamed Hassan at the Academy of Sciences for the Developing World (TWAS) argues that the nanotechnology boom will not lead to a divide between developed and developing countries due to the transformation of 21st century global science. Hassan says Brazil, China and India are swiftly developing nanotech capabilities. Instead, he warns of a South-South divide as poorer nations struggle to catch up. To avoid this, Hassan recommends that developing nations create networks between universities and research centres to share nanotech expertise.
