The long view of nanotechnology development: the National Nanotechnology Initiative at 10 years
A global scientific and societal endeavor was set in motion by the nanotechnology vision formulated in 1999 that inspired the National Nanotechnology Initiative (NNI) and other national and international R&D programs. Establishing foundational knowledge at the nanoscale has been the main focus of the nanotechnology research community in the first decade. As of 2009, this new knowledge underpinned about a quarter of a trillion dollars worldwide market, of which about $91 billion was in US products that incorporate nanoscale components. Nanotechnology is already evolving toward becoming a general-purpose technology by 2020, encompassing four generations of products with increasing structural and dynamic complexity: (1) passive nanostructures, (2) active nanostructures, (3) nanosystems, and (4) molecular nanosystems. By 2020, the increasing integration of nanoscale science and engineering knowledge and of nanosystems promises mass applications of nanotechnology in industry, medicine, and computing, and in better comprehension and conservation of nature. Nanotechnology’s rapid development worldwide is a testimony to the transformative power of identifying a concept or trend and laying out a vision at the synergistic confluence of diverse scientific research areas. This chapter provides a brief perspective on the development of the NNI since 2000 in the international context, the main outcomes of the R&D programs after 10 years, the governance aspects specific to this emerging field, lessons learned, and most importantly, how the nanotechnology community should prepare for the future.

The import of a research-oriented definition of nanotechnology
Definition of nanotechnology (set out in Nanotechnology Research Directions, 1999)1
Nanotechnology is the ability to control and restructure the matter at the atomic and molecular levels in the range of approximately 1–100 nm, and exploiting the distinct properties and phenomena at that scale as compared to those associated with single atoms or molecules or bulk behavior. The aim is to create materials, devices, and systems with fundamentally new properties and functions by engineering their small structure. This is the ultimate frontier to economically change materials properties, and the most efficient length scale for manufacturing and molecular medicine. The same principles and tools are applicable to different areas of relevance and may help establish a unifying platform for science, engineering, and technology at the nanoscale. The transition from single atoms or molecules behavior to collective behavior of atomic and molecular assemblies is encountered in nature, and nanotechnology exploits this natural threshold.
In 2010, the International Standardization Organization (ISO) Technical Committee 229 on nanotechnologies (ISO 2010) issued a definition of nanotechnology that essentially has the same elements as those of the 1999 definition: the application of scientific knowledge to manipulate and control matter in the nanoscale range to make use of size- and structure-dependent properties and phenomena distinct from those at smaller or larger scales. Full acceptance and use of the ISO definition in the environmental, health, and safety (EHS) community has not yet been resolved (Lövestam et al. 2010). Nevertheless, in 1999 as now, there has been a shared acceptance of the value of clearly defining nanotechnology to support common language and purpose for scientific discourse, engineering, education, manufacturing, commerce, regulation, and tracking of investments. Defining the long-term vision for nanotechnology development is especially critical because of nanotechnology’s rapid emergence as a fundamentally new scientific and engineering paradigm and because of its broad implications for societal wellbeing.
The 1999 unifying definition of and long-term vision for nanotechnology paved the way for the US National Nanotechnology Initiative (NNI), announced in January 2000. The main reasons for beginning the NNI were to fill major gaps in fundamental knowledge of matter and to pursue the novel and economic applications anticipated for nanotechnology. Coherent and sustained R&D programs in the field were soon announced by other nations: Japan (April 2001), Korea (July 2001), the European Community (March 2002), Germany (May 2002), China (2002), and Taiwan (September 2002). Over 60 countries established programs at a national level between 2001 and 2004, partially inspired or motivated by the NNI. However, the first and largest such program was the NNI itself. Its cumulative funding since 2000 of more than $12 billion, including about $1.8 billion in 2010, places the NNI second only to the space program in the US civilian science and technology investments. This 2010 international study, involving experts from over 35 countries, aims to redefine the goals for nanotechnology development for the next decade.

The number of researchers and workers involved in one domain or another of nanotechnology was estimated at about 400,000 in 2008, of which about 150,000 were in the United States. The estimate made in 2000 that there would be 2 million nanotechnology workers worldwide by about 2015 (800,000 in the United States) would have been realized if the 25% rate growth had continued. The initial 2000 estimation for quasi-exponential growth in the nanotechnology workforce (Roco 2003a) held up to 2008, and because of new generations of nanotechnology products envisioned to enter the market within the next few years, it is expected to continue.
- 2.The number of Science Citation Index (SCI) papers reflecting discoveries in the area of nanotechnology reached about 65,000 in 2008 as compared to 18,085 in 2000, based on a title–abstract keyword search (Chen and Roco 2009). The increase is rapid and uneven around the world, as suggested by Fig. 1. About 4.5% of SCI papers published in 2008 in all areas included nanoscale science and engineering aspects.
- 3.Inventions reflected by the number of patent applications filed in the top 50 depositories was about 13,000 in 2008 (of which 3,729 were filed at the US Patent and Trade Office, USPTO), as compared to about 1,200 in 2000 (of which 405 were filed at USPTO) (Huang et al. 2004, 2005), with an annual growth rate of about 35%, as shown in Fig. 2. The patent applications in over 50 national or international patent depositories were searched by using the title–abstract keyword search. About 0.9% of patent applications published worldwide, and about 1.1% at USPTO in 2008 in all areas, included nanoscale science and engineering aspects.
- 4.The value of products incorporating nanotechnology as the key component reached about $200 billion in value worldwide in 2008, of which about $80 billion was in the US (these products relied on relatively simple nanostructures). The estimation made in 2000 (Roco and Bainbridge 2001) for a product value of $1 trillion by 2015, of which $800 billion would be in the US, still appears to hold (see Fig. 3). The market is doubling every 3 years as a result of successive introduction of new products. The Lux Research estimate for the 2009 market worldwide was about $254 billion (Chapter 13, Sect. 13.8.11 in Roco et al. 2010), about on the 2000 estimated curve, although the Lux estimate for the value of US nanotechnology products in 2009 of about $91 billion was about 10% under the 2000 estimated growth curve.
Global nanotechnology R&D annual investment from private and public sources reached about $15 billion in 2008, of which about $3.7 billion was in the US, including the Federal Government contribution of about $1.55 billion.
Global venture capital investment in nanotechnology reached about $1.4 billion in 2008, of which about $1.17 billion was in the US (courtesy Lux Research 2010). Venture capital funds decreased about 40% during the 2009 financial crisis (see Chapter 13, Sect. 13.8.11 in Roco et al. 2010).

The specific annual Federal R&D nanotechnology expenditure per capita has grown from about $1 in fiscal year (FY) 2000 to about $5.7 in 2010.
The fraction of the Federal R&D nanotechnology investment as compared to all actual Federal R&D expenditures grew from 0.39% to about 1.5% in 2008.
Qualitative changes also are important to evaluating the impact of the NNI, even if there is no single indicator to characterize them. These include (1) the creation of a vibrant multidisciplinary, cross-sector, international community of professionals and organizations engaged in various dimensions of the nanotechnology enterprise; (2) changes in the scientific research culture that are coming about through energizing interdisciplinary academic research collaborations with industry and the medical field; and (3) increasingly unified concepts for engineering complex nanostructures “from the bottom up” for new materials, biology and healthcare technologies, digital information technologies, assistive cognition technologies, and multicomponent systems.
Two foundational steps in nanotechnology development
The first foundational phase (2001–2010), which was focused as anticipated on inter-disciplinary research at the nanoscale, took place in the first decade after defining the long-term vision. Its main results are discovery of new phenomena, properties, and functions at the nanoscale; synthesis of a library of components as building blocks for potential future applications; tool advancement; and improvement of existing products by incorporating relatively simple nanoscale components. This phase, dominated by a science-centric ecosystem, might be called “Nano 1.”
The second foundational phase (2011–2020), will be focused on nanoscale science and engineering integration, is projected to transition toward direct measurements with good time resolution, science-based design of fundamentally new products, and general-purpose and mass use of nanotechnology. The focus of R&D and applications is expected to shift toward more complex nanosystems, new areas of relevance, and fundamentally new products. This phase is expected to be dominated by an R&D ecosystem driven by socio-economic considerations; it might be called “Nano 2.”

After 2020, nanotechnology R&D is projected to develop closely with other emerging and converging technologies, creating new science and engineering domains and manufacturing paradigms (Roco 2002; Roco and Bainbridge 2003). In 1999/2000, a convergence was reached in defining the nanoscale world because typical phenomena in material nanostructures were better measured and understood with a new set of tools, and new nanostructures had been identified at the foundations of biological systems, nanomanufacturing, and communications. The new challenge for the next decade is building systems from the nanoscale that will require the combined use of nanoscale laws, biological principles, information technology, and system integration. After 2020, one may expect divergent trends as a function of system architectures. Several possible divergent trends are system architectures based on guided molecular and macromolecular assembling, robotics, biomimetics, and evolutionary approaches.
Genesis and structure of the National Nanotechnology Initiative
As the then Chair of the NSTC’s Interagency Working Group on Nanoscale Science, Engineering, and Technology (IWGN),2 the author had the opportunity to propose the NNI with an annual budget of about 1/2 billion dollars on March 11, 1999, at a meeting of the White House Economic Council (EC) and the Office of Science and Technology Policy (OSTP) as part of a competition for a national research priority to be funded in FY 2001. The approval process moved to the Office of Management and Budget (OMB) in November 1999, the Presidential Council of Advisors in Science and Technology (PCAST) in December 1999, and the Executive Office of the President in January 2000. Hearings were held in the House and Senate of the United States Congress in the Spring of 2000. In November 1999, the OMB recommended nanotechnology as the only new R&D initiative for FY 2001. On December 14, 1999, PCAST highly recommended that the President fund nanotechnology R&D. Thereafter, it was a quiet month: the Executive Office of the President advised the working group to restrain from speaking to the media because a White House announcement would be made.
President Clinton announced the NNI at a speech at the California Institute of Technology (Caltech) in January 2000, asking listeners to imagine the new world that nanotechnology could make possible. After his speech, the IWGN moved firmly to prepare the Federal plan for R&D investment in nanotechnology and to identify key opportunities and potential participation of various agencies in the proposed initiative. House and Senate hearings brought the needed recognition and feedback from Congress. Representing the working group, the author spoke to major professional societies (the American Chemical Society, the Institute for Electric and Electronics Engineering, the American Society of Mechanical Engineering, and the American Institute of Chemical Engineering), and attended national meetings in about 20 countries to introduce the new US nanotechnology initiative. The NNI has been implemented since FY 2001, with unbroken support from the Clinton, Bush, and Obama Administrations.
A challenge in the early years of the initiative, with so many new developments, was maintaining consistency, coherence, and original thinking. The definition of nanotechnology, the initiative’s name, and the name of the National Nanotechnology Coordination Office (NNCO) were decided in 1999–2000. The NNI’s name was proposed on March 11, 1999, but it was held under “further consideration” until the Presidential announcement, due to concerns from several professional societies and committees that it did not explicitly include the word “science.” The simple name “NNI” was selected to better show its relevance to society.

The NNI organizing principles
The NNI’s long-term view of nanotechnology development aims to enable exploration of a new domain of scientific knowledge and incorporation of a transformational general-purpose technology into the national technological infrastructure, with a twenty-year view to reach some degree of systematic control of matter at the nanoscale and mass use (Roco 2007). The vision that “systematic control of matter at the nanoscale will lead to a revolution in technology and economy for societal benefit” is still the guiding principle of the initiative.
During the 10-year time span of FYs 2001–2010, a thriving interdisciplinary nanotechnology community of about 150,000 contributors has emerged in the US, along with a flexible R&D infrastructure consisting of about 100 large nanotechnology-oriented R&D centers, networks, and user facilities, and an expanding industrial base of about 3,000 companies producing nanotechnology-enabled products. Considering the complexity and rapid expansion of the US nanotechnology infrastructure, the participation of a coalition of academic, industry, business, civic, governmental, and nongovernmental organizations in nanotechnology development is becoming essential and complementary to the centralized approach of the NNI. The leadership role of the Federal government through the NNI must continue in support of basic research, restructuring the education pipeline, and guiding responsible development of nanotechnology as a transformative scientific schema, as envisioned in 2000. At the same time, however, the emphasis of government leadership in nanotechnology development is changing toward increasing support of R&D for innovation, nanomanufacturing, and societal benefit, while the private sector’s responsibility is growing for funding R&D in nanotechnology applications. Since 2006, private nanotechnology R&D funding in the US has exceeded public funding.
Several means to ensure accountability are built into the 21st Century Nanotechnology Research and Development Act that governs the NNI (P.L. 108–153, 15 USC 7501, of the US Congress, December 3, 2003). With extensive input from NSET Subcommittee agency members, the NNI organizations submit to Congress every February an annual report on the NNI and a combined nanotechnology budget request. OMB manages and evaluates the NNI budget crosscut. Following the Nanotechnology Research Directions report published in 2000, NNI leadership prepares a Strategic Plan every 3 years (2004, 2007, and 2010). The NNI is evaluated every 3 years by the National Research Council of the National Academies and periodically by PCAST in its role as the National Nanotechnology Advisory Panel. Ad hoc evaluations by the Government Accountability Office and other organizations help ensure best use of taxpayer funds and respect for the public interest.
The organizing principles of the NNI have undergone two main stages between 2001 and 2010, and a third stage is projected to begin in FY 2011:
Nanostructured materials by design
Manufacturing at the nanoscale
Chemical–biological–radiological–explosive detection and protection
Nanoscale instrumentation and metrology
Nano-electronics, -photonics, and -magnetics
Healthcare, therapeutics, and diagnostics
Efficient energy conversion and storage
Microcraft and robotics
Nanoscale processes for environmental improvement
Focused research programs and major infrastructure initiatives in the first 5 years led to the formation of the US nanoscale community, a strong R&D infrastructure, and new nanotechnology education programs.
Fundamental nanoscale phenomena and processes
Nanoscale devices and systems
Instrumentation research, metrology, and standards for nanotechnology
Major research facilities and instrumentation acquisition

c. Beginning in FY 2011, the NNI will introduce three research and development “signature initiatives” for important long- and short-term application opportunities3: (1) Nanotechnology Applications for Solar Energy, (2) Sustainable Nanomanufacturing, and (3) Nanoelectronics for 2020 and beyond. Other research “signature initiatives,” and plans to enhance the innovation ecology and societal outcomes of nanotechnology, are under consideration (NSTC/NSET 2010).

Governance of nanotechnology
Governing any emerging technology requires specific approaches (Roco 2008), and for nanotechnology in particular, consideration of its potential to fundamentally transform science, industry, and commerce, and of its broad societal implications. It should be stressed that the technology governance approach needs to be focused on many facets, not only on risk governance (Roco and Renn 2008). Properly taking into account the roles and views of the various stakeholders in the society—including their perceptions of science and technology, human behavior factors, and the varying social impacts of the technology—is an increasingly important factor in the development of any emerging, breakthrough technology. Optimizing societal interactions, R&D policies, and risk governance for nanotechnology development can enhance economic competitiveness and democratization, but all stakeholders must be equally invested. Chapter 13 (Roco et al. 2010) on innovative and responsible governance discusses four basic functions of the governance and four basic structural levels. Below are illustrated the application of the four basic functions or characteristics of effective governance of nanotechnology, that it should be (1) transformative, (2) responsible, (3) inclusive, and (4) visionary.
Transformative and responsible development of nanotechnology
In examples of programs focused on studying and advancing societal aspects of nanotechnology R&D, in 2004-2005, NSF began establishing new kinds of networks with national goals and outreach, focused on high school and undergraduate nanotechnology education (the National Centers for Learning and Teaching in Nanoscale Science and Engineering), nanotechnology in society (the Centers for Nanotechnology in Society), and informal nanotechnology science education (the Nanoscale Informal Science Education Network). Other aspects of pursuing responsible development of nanotechnology include the NNI’s considerable and growing focus on nanotechnology environmental, health, and safety (nanotechnology EHS or nanoEHS) research its interagency and international consultations on standards and regulation.
To support the NNI agency focus on the issues of transformative and responsible development of nanotechnology, the NSET Subcommittee established the Nanomanufacturing, Industry Liaison, and Innovation (NILI), Nanotechnology Environmental and Health Issues (NEHI), and Global Issues in Nanotechnology (GIN) Working Groups. The transformative function for nanotechnology development is addressed in Roco et al. (2010) in Chapters 1 and 2 for tools, Chapter 3 for manufacturing, Chapters 7–11 for applications, and Chapter 13 for innovation. The responsible function for nanotechnology development is discussed in Chapter 4 for nanotechnology environmental, health, and safety, in Chapters 5 and 6 for sustainable development, and in Chapter 13 for nanotechnology ethical, legal, and social issues (ELSI).
Inclusiveness in the development and governance of nanotechnology
Regarding international aspects of nanotechnology governance, a multidisciplinary, international forum is needed to better address the nanotechnology scientific, technological, and infrastructure development challenges. Optimizing societal interactions, R&D policies, and risk governance for the converging new technologies can enhance economical competitiveness and democratization. The International Risk Governance Council (IRGC 2006) has provided an independent international perspective for a framework for identification, assessment, and mitigation of risk.

The Presidential Council of Advisors in Science and Technology (PCAST 2005) endorsed the governing approach adopted by NNI: “(The Council) supports the NNI’s high-level vision and goals and the investment strategy by which those are to be achieved.”
“NNI is a new way to run a national priority,” Charles Vest, president of the National Academy of Engineering, at the March 23, 2005, PCAST meeting reviewing the NNI for Congress.
PCAST (2010): “NNI… has had “catalytic and substantial impact” on the growth of the US nanotechnology industry”; “…[I]n large part as a result of the NNI the US is today, by a wide range of measures, the global leader in this exciting and economically promising field.”
“The NNI story could provide an useful case study for newer research efforts into fields such as synthetic biology, renewable energy, or adaptation to climate change. These are the kind of areas in which science, applications, governance, and public perception will have to be coordinated across several agencies…[F]or emerging areas like this, the concept of NNI is a good one,” David Rejeski, director of the S&T Innovation program at the Woodrow Wilson International Center for Scholars in a Nature interview on September 2, 2010 (Lok 2010).
“Nanotechnology has become a model and an intellectual focus in addressing societal implications and governance methods of emerging new technologies,” David Guston (2010)
Objectives that have not been fully realized after 10 years
General methods for achieving nanoscale “materials by design” and composite materials: the delay is because the direct theory, modeling, and simulation tools and measurement techniques with sufficient resolution were not ready.
Sustainable development projects: nanotechnology for energy solutions received momentum only after 5 years, nanotechnology for water filtration and desalination and climate research still has only limited funding; it is not clear if the delay in funding nanotechnology R&D for these topics is because of insufficient pull and collaboration from respective stakeholders that are less organized than in other sectors.
Widespread public awareness of nanotechnology; the awareness figure remains low, at about 30%; this is a challenge for increasing public participation in governance.
On target in 2010, even if doubted in 2000
A steep growth rate in scientific papers and inventions: the rate for nanotechnology has been quasi-exponential (23–35% annually), at rates at least two times higher than the average for all scientific fields.
Significant advancement in interdisciplinary research and education: nanotechnology R&D has led to creation of many multidisciplinary projects, organizations, and communities.
Estimation that US nanotechnology R&D investment will grow by about 30% annual growth rate (government and private sector, in-depth vertical development and new areas of horizontal development): the rate (see earlier in this paper) held at 25–30% from 2000 to 2008.
Better than expected after 10 years
Major industry involvement after 2002–2003: as examples, more than 5,400 U.S. companies had papers, patents, and/or products in 2008 (see Chapter 13); and Moore’s law has continued for the past ten years, despite serious doubts raised in 2000 about the trend being able to continue into the nanoscale regime.
Unanticipated discoveries and advances in several science and engineering fields, including plasmonics, metamaterials, spintronics, graphene, cancer detection and treatment, drug delivery, synthetic biology, neuromorphic engineering, and quantum information systems.
The formation and growing strength of the international nanotechnology community, including in nanotechnology EHS and ELSI: these developments have surpassed expectations, and the debut of governance studies was unanticipated.
Main lessons learned after 10 years
There is a need for continued, focused investment in theory, direct measurement, and simulation at the nanoscale; nanotechnology is still in the formative phase.
Besides R&D in new nanostructured metals, polymers, and ceramics, excellent opportunities for nanotechnology R&D exist in classical industries, such as textiles, wood and paper, plastics, and agricultural and food systems. Improved mechanisms are needed for public–private partnerships to establish consortia or platforms for targeted development programs.
There is a need to better connect science and engineering to translational research and creation of jobs.
There is a need to continue to increase multistakeholder and public participation in nanotechnology governance.
The vision for the future of nanotechnology research and development to 2020—as a whole and in each domain (tools, manufacturing, applications, infrastructure, governance, etc.)—is presented in Roco et al. 2010. The goal has been to provide a long-term and timely vision for nanotechnology R&D, with input from leading experts in the nanotechnology community.
Overall, it appears that the NNI has been the major driver for nanoscience and nanotechnology developments and applications in the US and in the World for close to a decade, but that many nations besides the US are continuing to rapidly expand their nanotechnology-related R&D programs in recognition of the fundamental scientific, economic, and social value of doing so.
Besides impacting products, tools, and healthcare, it is inevitable that nanotechnology R&D will also impact learning, imagination, infrastructure, inventions, public acceptance, culture, laws, and the architecture of various other socio-economic factors. From 1997 to 2000, the US scientific establishment developed a vision for nanotechnology R&D, and in the first 10 years of the NNI, 2001–2010, that vision has become a reality. The report by Roco et al. (2010) is intended to extend that vision into the next 10 years, to 2020 (and beyond).
A main impetus for the original development of the NNI was the long-term view, based on an intellectual drive toward exploiting new phenomena and processes, developing an unified science and engineering platform from the nanoscale, and using molecular and nanoscale interactions to radically improve the efficiency of manufacturing. Complementary to these goals has been the promise of broad societal benefit from pursuing nanotechnology R&D, including an anticipation of $1 trillion/year by 2015 of products where nanotechnology plays a key role, which would require 2 million workers with nanotechnology-related skills. Because the rate of market increase is expected to follow the trends in papers and patents of about a 25% increase per year in the previous 10 years, one may estimate that by 2020, there will be about $3 trillion in products that incorporate nanotechnology as a key performance component. The nanotechnology markets and related jobs are expected to double each 3 years.
Nanotechnology is evolving toward new scientific and engineering challenges in areas such as assembly of nanosystems, nanobiotechnology and nanobiomedicine, development of advanced tools, environmental preservation and protection, and pursuit of societal implication studies. All trends for papers, patents, and worldwide investments are still expected to have quasi-exponential growth, with potential inflexion points occurring within several years. There is a need for continuing long-term planning, interdisciplinary activities, and anticipatory measures involving interested stakeholders.
From a focus on creating single nanoscale components to a focus on creating active, complex nanosystems
From specialized or prototype research and development to mass use in advanced materials, nanostructured chemicals, electronics, and pharmaceuticals
From applications in advanced materials, nanoelectronics, and the chemical industry, expanding into new areas of relevance such as energy, food and agriculture, nanomedicine, and engineering simulations from the nanoscale where competitive solutions are expected
From starting at rudimentary first-principles understanding of the nanoscale to accelerating development of knowledge, where the rate of discovery remains high and significant changes continually occur in application areas
From almost no specialized infrastructure to well-institutionalized programs and facilities for nanotechnology research, education, processes, manufacturing, tools, and standards
While expectations from nanotechnology may have been overestimated in the short term, the long-term implications for the impact of nanotechnology on healthcare, productivity, and environmental protection appear now to be underestimated, provided that proper consideration is given in coming years to educational and social issues.
It will be imperative over the next decade to focus on four distinct aspects of nanotechnology development that are discussed in this volume: (1) better comprehension of nature, leading to knowledge progress; (2) economic and societal solutions, leading to material progress; (3) international collaboration on sustainable development, leading to global progress; and (4) people working together for equitable governance, leading to moral progress.
(Roco et al. 1999).
The IWGN was superseded in August 2000 by the Nanoscale Science, Engineering and Technology (NSET) Subcommittee of the NSTC Committee on Technology. In 1999 Neil Lane was the Director of OSTP, and Tom Kalil was Deputy Director of the White House National Economic Council and the White House co-chair of the IWGN. Jim Murday was the secretary of IWGN.
