WASHINGTON, D.C. -- "Nanotechnology has the potential to generate enormous health benefits for the more than five billion people living in the developing world," according to Dr. Peter A. Singer, senior scientist at the McLaughlin-Rotman Centre for Global Health and Professor of Medicine at University of Toronto. "Nanotechnology might provide less-industrialized countries with powerful new tools for diagnosing and treating disease, and might increase the availability of clean water."
"But it remains to be seen whether novel applications of nanotechnology will deliver on their promise. A fundamental problem is that people are not engaged and are not talking to each other. Business has little incentive—as shown by the lack of new drugs for malaria, dengue fever and other diseases that disproportionately affect people in developing countries—to invest in the appropriate nanotechnology research targeted at the developing world. Government foreign assistance agencies do not often focus, or focus adequately, on science and technology. With scant public awareness of nanotechnology in any country, there are few efforts by nongovernmental organizations (NGOs) and community groups to examine how nanotechnology could be directed toward, for example, improving public health in the developing world."
Dr. Singer’s group in Toronto published a study in 2005 identifying and ranking the ten nanotechnologies most likely to benefit the developing world in the near future. Nanotechnology applications related to energy storage, production, and conversion; agricultural productivity enhancement; water treatment and remediation; and diagnosis and treatment of diseases topped the list. Dr. Singer’s group has also shown that there is a surprising amount of nanotechnology R&D activity in several developing countries, and that these nations are directing their nanotechnology innovation systems to address their more pressing needs.
"Countries like Brazil, India, China and South Africa have significant nanotechnology research initiatives that could be directed toward the particular needs of the poor. But there is still a danger—if market forces are the only dynamic—that small minorities of people in wealthy nations will benefit from nanotechnology breakthroughs in the health sector, while large majorities, mainly in the developing world, will not," noted Dr. Andrew Maynard, chief science advisor for the Woodrow Wilson Center’s Project on Emerging Nanotechnologies. "Responsible development of nanotechnology must include benefits for people in both rich and poor nations and at relatively low cost. This also requires that careful attention be paid to possible risks nanotechnology poses for human health and the environment."
Dr. Piotr Grodzinski, director of the Nanotechnology Alliance for Cancer at the National Cancer Institute, National Institutes of Health (NIH) discussed the impact of nanotechnology on diagnostics and therapies for cancer. He said, "It is my belief that nanomaterials and nanomedical devices will play increasingly critical and beneficial roles in improving the way we diagnose, treat, and ultimately prevent cancer and other diseases. But we face challenges; the complexity of clinical implementation and the treatment cost may cause gradual, rather than immediate, distribution of these novel yet effective approaches."
"For example, in the future, it may be possible for citizens in Bangladesh to place contaminated water in inexpensive transparent bottles that will disinfect the water when placed in direct sunlight, or for doctors in Mexico to give patients inhalable vaccines that do not need refrigeration," Dr. Maynard noted. "Nanotechnologies could revolutionize health care in developing countries and make treatments more readily available for diseases that claim millions of lives around the world each year."
The discussion took place at a program entitled "Using Nanotechnology to Improve Health Care in Developing Countries," held at the Woodrow Wilson International Center for Scholars. The event was organized by the Wilson Center’s Project on Emerging Nanotechnologies and Global Health Initiative. It was moderated by Dr. Jeff Spieler, chief of research, technology and utilization for the Office of Population and Reproductive Health at the U.S. Agency for International Development (USAID).
Dr. Piotr Grodzinski is director of National Cancer Institute (NCI) Nanotechnology Alliance for Cancer in Bethesda, Maryland. He is an internationally recognized authority in the areas of bio- and nano-chip assays and microfluidics, and has built and led research efforts in private industry and national labs. Dr. Grodzinski received a Ph.D. in Materials Science from the University of Southern California, Los Angeles in 1992.
Dr. Andrew Maynard is chief science advisor for the Project on Emerging Nanotechnologies. His research interest in nanomaterials started in the late 1980s, while working on his doctorate in ultrafine aerosol analysis at the University of Cambridge in the UK. Through his work with the UK Health and Safety Executive, the U.S. National Institute of Occupational Safety and Health and the U.S. National Nanotechnology Initiative, he has led current science-based efforts to understand and manage the potential risks of nanotechnology. Dr. Maynard is considered one of the foremost international experts on addressing possible nanotechnology risks and developing safe nanotechnologies, and brings a much-needed science perspective to a field fraught with uncertainty.
Dr. Peter A. Singer is senior scientist and co-director of the Program on Life Sciences, Ethics and Policy at the McLaughlin Rotman Centre for Global Health, University Health Network; professor of Medicine, University of Toronto; and a distinguished investigator of the Canadian Institutes of Health Research. He studied internal medicine at the University of Toronto, medical ethics at the University of Chicago, public health at Yale University, and management at Harvard Business School. His contributions have included improvements in quality end of life care, fair priority setting in healthcare organizations, teaching bioethics, pandemic influenza planning, global biosecurity, and harnessing life sciences and emergent technologies to improve health in developing countries.
Dr. Jeff Spieler is chief of research, technology and utilization for the Office of Population and Reproductive Health at the U.S. Agency for International Development (USAID). He joined USAID in 1983 as the senior biomedical research advisor in population after spending 11 years at the Special Programme of Research, Development and Research Training in Human Reproduction of the World Health Organization (WHO). Before joining the WHO, he worked for 5 years as a bench scientist at Lederle Laboratories Pharmaceutical Company in Pearl River, NY. Dr. Spieler received a B.S. in Zoology from the University of Florida in 1967, a M.S. in Zoological Sciences and Reproductive Biology from Rutgers University in 1971, and an Honorary Doctorate in Public Service from the University of Florida in 2002.

About Nanotechnology
Nanotechnology is the ability to measure, see, manipulate and manufacture things usually between 1 and 100 nanometers. A nanometer is one billionth of a meter; a human hair is roughly 100,000 nanometers wide.
The Project on Emerging Nanotechnologies is an initiative launched by the Woodrow Wilson International Center for Scholars and The Pew Charitable Trusts in 2005. It is dedicated to helping business, government and the public anticipate and manage possible health and environmental implications of nanotechnology.

The Global Health Initiative at the Woodrow Wilson International Center for Scholars brings practitioners, scientists, scholars, and policymakers together in a neutral forum to discuss the most pressing health issues of the 21st century in the hope of ultimately increasing understanding of health issues and inspiring policy decisions that will improve the lives of citizens around the world.
