Preface

The National Research Council (NRC) was asked by the U.S. Congress to conduct the first triennial evaluation of the National Nanotechnology Initiative (NNI);1 assess the need for standards, guidelines, or strategies for ensuring the responsible development of nanotechnology; and consider the technical feasibility of molecular self-assembly for the manufacture of materials and devices at the molecular scale. The full statement of task is given in Appendix A.

APPROACH TO AND SCOPE OF THIS STUDY

To conduct this study, the NRC appointed the Committee to Review the National Nanotechnology Initiative, whose members’ expertise ranged from nanoscale science and engineering to industrial research and development (R&D) and encompassed interdisciplinary research, business management, biomedicine and human health, public and environmental safety, national defense, international benchmarking, transfer of technology for commercialization, intellectual property issues, and the societal and ethical implications of nanotechnology; see Appendix B.

To gather information on and gain insight into the multiagency collaborations and extensive R&D programs associated with the NNI, the committee held a series of public workshops participated in by members of the broader NNI-related com-

A review of the National Nanotechnology Initiative by the NRC in 2002 was published in Small Wonders, Endless Frontiers: A Review of the National Nanotechnology Initiative (National Academy Press, Washington, D.C., 2002).

munity, including representatives of the federal agencies participating in the NNI. The meeting and workshop agendas along with lists of participants are provided in Appendix C. Summaries of the presentations made at the workshop on responsible development are presented in Appendix D. Appendix E defines the acronyms used in the report. In addition to its four workshops the committee held a series of closed private sessions and telephone conferences to discuss its findings and to develop its conclusions and recommendations.

Given the length and breadth of its charge (see Appendix A), the committee sought an approach that would give an accurate picture of the NNI and its accomplishments today and also allow identification of opportunities for improvement in the future (Chapter 1), as well as enable assessment of the relative position of U.S. nanotechnology R&D compared to that of other nations (Chapter 2) and a discussion of the impact of nanotechnology on the U.S. economy (Chapter 3). The complexity and detail of the set of programmatic tasks and the quite different requirements posed by the two additional tasks, on the responsible development of nanotechnology (Chapter 4) and molecular self-assembly (Chapter 5), added considerable complexity to the task. To provide a useful analysis, the committee focused only on topics accessible to examination and for which at least some reliable data were available. It notes that—considered in light of the major benefits anticipated—the NNI represents a comparatively young undertaking whose results will take time to develop, and also to measure quantitatively. Although the committee’s treatment of the many topics in its charge is uneven, it dealt with each to the extent possible, except as noted below.

In its discussion of both the relative position of the United States worldwide in nanoscale R&D and the economic impact of nanotechnology, the committee chose to consider not only NNI-related R&D, but also research supported by private and public funds, as well as research supported by federal funds not associated with the NNI, given that nanotechnology R&D is being conducted at industrial R&D laboratories and that sources of support for nanotechnology R&D also include private foundations and venture capital funds—and that isolating the contributions of each was beyond the committee’s ability to accomplish for this study.

With respect to responsible development of nanotechnology, the committee focused on tangible concerns related to environmental, health, and safety issues and also touched on the importance of broadly targeted efforts in communication on and education about societal concerns. As a result of its reflections on and discussion of what is regarded as the more futuristic aspects of nanotechnology—such as the use of nanotechnology in developing artificial intelligence, and similar topics popularized in science fiction—the committee decided that an assessment of such topics in the context of a need for standards and guidelines would be premature and speculative at best. Therefore, the committee chose to address potential real

risks rather than perceived risks pertaining to nanotechnology. The committee points out that several interesting observations on societal implications are presented in the individually authored signed summaries of presentations made at its Workshop on Responsible Development of Nanotechnology (see Appendix D). The committee is convinced that delineating and addressing the kinds of issues raised by such observations is critical to realizing the full potential of nanotechnology.

This study does not include a comprehensive technical assessment of the NNI to date, beyond the benchmarking and examination of economic impact reported in Chapters 2 and 3. The committee was hampered in its efforts by a number of things: the interdisciplinary nature of nanotechnology R&D, which includes a mix of the physical sciences, engineering, technology, and biomedical sciences; the impossibility of isolating and measuring the contributions of individual nanoscale R&D programs; the long timescales needed to translate to practical benefits the results of nanoscale R&D that is still in its infancy; and the enormous technical breadth of the approximately $1.1 billion in R&D carried out annually. However, the committee did receive anecdotal evidence of significant achievements across many fields, including information presented at its workshop on scientific achievements, and makes reference to some of those at points in the report. The committee is convinced that the R&D infrastructure now being developed under the NNI will help make possible technical achievements whose impact will become apparent and amenable to study, over time.

In addition, the committee did not attempt to assess the funding levels at each NNI-participating agency in terms of their adequacy for meeting stated program goals. Such an evaluation would have required a program by program analysis of each agency—an effort beyond the committee’s resources and one also precluded by the lack of consistent reporting and tracking of funds requested, authorized, and expended within and across agencies. The committee reiterates, moreover, that it is too early to fully assess, at this early stage in nanoscale R&D, technical accomplishments and goals achieved as a result of investments made under the NNI.

ACKNOWLEDGMENTS

To better calibrate the data presented in the workshops, individual committee members contacted corporate leaders in various nanotechnology sectors and operations, from start-up companies to multinational corporations, to seek an industry perspective on commercial nanotechnologies, nanotechnology R&D, and NNI programs. In this regard the committee is grateful to the following participants in that process: Larry Bock, Nanosys; Uma Chowdhry and Krishna Doraiswamy, DuPont; Daniel Gamota, Motorola; Paolo Gargini, Intel Corporation;

The National Nanotechnology Initiative (NNI) was created in 2000 to focus and coordinate the nanoscience and nanotechnology research and development (R&D) activities being funded by several federal agencies. The purpose of the NNI is to marshal these research activities in order to accelerate responsible development and deployment of nanotechnology for economic benefit and national security. To take stock of the progress of the NNI, Congress, in P. L. 108-153, the 21st Century Nanotechnology Research and Development Act, directed the National Research Council to carry out a review of the program every three years. This report presents the results of the first of those reviews, which addresses the economic impact of nanotechnology developments and provides a benchmark of U.S. R&D efforts relative to those undertaken by foreign competitors. In addition, the report offers an assessment of the current status of responsible development of nanotechnology and comments on the feasibility of molecular self-assembly.
