Small Things and Big Changes in the Developing World

Nanoscience and nanotechnology have been embraced by developing countries with governmental support--a paradigm shift in science-based development strategies. In this Policy Forum, the authors describe the trends and urge alliances between North and South (without favoring the wealthy consumers) and with the least-developed nations to meet social and environmental goals. Investments by governments of developing countries in nanoscience and nanotechnology are paving the way for better science and solutions to problems of basic living, as well as offering excellent returns on investment.
