- i.e. semiconductor, chemical, biotechnology,
aerospace - What is the use of it?
- i.e. A better computer chip, method to treat
diseases, stronger material for aerospace
applications - What are the obstacles?
- i.e. Quantum effects at nanoscale, unknown
toxicity, public acceptance - What is the key strategy?
- i.e. focusing on the beneficial applications
of nanotechnology - What are the resources?
- i.e. government funding, private investment
- What is the time frame?
- i.e. a 5- 10 year plan

5 Scientific Development Factors
- Multi-disciplinary nature of nanoscience and
nanotechnology - More funding are needed to realize the full
potential of nanoscience - Limited resources are available for
nano-manufacturing production - Need to focus on a certain list of priority of
research topics, rather than - scattered resources every where.
- Need to develop internationally accepted
nomenclature - Need to develop internationally accepted
standards for research methodology - and quality control and quality assurance.
- Need to collaborate internationally, while
strengthen expertise locally

6Economic Factors
- Small technology-based entrepreneurial
companies as a source of - innovation and generator of jobs.
- Investors shy away from applications with
lengthy time periods - between R D and market penetration.
- Small companies at risk through the valley
of death in funding and - the period nexus between public policy and
industry realities. - Public/Private funding i.e. Incubator facility
and seed capital needed to - nurture start-up companies with promising
technology -
- Building an accessible labor pool of
nanotechnologists and workforce in - nanotechnology to create jobs and foster
economic growth.

7 Public Relations Factors
- Limited public awareness of nature and
potential of nanotechnology - Public funding to date focused on R D- Ratio
of R D to successful - product development is low
- Limited resources focusing on
nano-manufacturing Commercialization's -
- Government has not yet fully recognized
barriers that could be assisted - through increased public support
- Government support for nanotechnology
innovation, i.e. FDA stamp of - approval that a discrete nanomaterial is
approved for market. - Product liability guidelines for
nanotechnology to clarify ambiguity - surrounding market opportunities for
nanotechnology products

9Challenges in developing international
nomenclature/ standards
- Communication across multi-disciplines
- National and international geo-political
differences - Intellectual Property protection
- Confidential business information
- Lack of funding for this long term endeavor
- Concern about potential government regulations
and public policy
International Association of Nanotechnology by
Lloyd L. Tran
10Why International Standards are needed ?
- The Standard Project will develop
interoperability specifications for
nanomaterials, devices and nanoscale structures
and systems. - To set international standards for testing
methods and processes so data is reported
uniformly and results can be compared and
verified - This will help researchers, designers,
manufacturers and suppliers as well as customers
to communicate effectively and harmonize best
practices worldwide. - To optimize the manufacturing processes while
ensure the trust and confidence of customers and
public at large - Without standards the emerging field cannot
grow to become an major industry.

11 International nomenclature and standards in
Nanotechnology are urgently needed for
- Research laboratory
- Publication
- Patent Protection
- Communication
- Clinical study
- Manufacturing
- Commercialization

25Toxic Substances Control Act 15 U.S.C. s/s 2601
et seq. (1976)
- The Toxic Substances Control Act (TSCA) of
1976 was enacted by Congress to give EPA the
ability to track the 75,000 industrial chemicals
currently produced or imported into the United
States. - EPA repeatedly screens these chemicals and can
require reporting or testing of those that may
pose an environmental or human-health hazard. - EPA can ban the manufacture and import of
those chemicals that pose an unreasonable risk.
