NANO-SAFETY [08 October 2007]

the properties of each of the materials begin to change. The realm of properties between bulk and atomistic are unknown or ill defined. This region of mesomaterial properties (between bulk and quan- tum) must be addressed and quantified. This task is not unlike developing a new Handbook of Physics and Chemistry with the onerous job of describing historically single value constants as multi-dimensional parameters. The scope of the effort is enormous and beyond the capability of any single organization to accomplish. While the overall effort to determine the nano properties belongs within an organization like the National Institute of Standards and Technology (NIST), the effort needs to begin with an agree- ment on what will be pursued. Although preliminary discussions with NIST have taken place over the last two years, there has not been a strong incentive to address the total issue. Now, NANO-SAFETY is one driving force. In July 2007, the International Technology Roadmap for Semiconductors (ITRS) committee held meetings on the revision of the ITRS. Lack of having fundamental properties for materials in the nanoscale range was identified as a critical item that needs to be addressed to enable continued semi- conductor technology progress. This requirement from a key manufacturing industry becomes an addi- tional driving force. Recommendation: Establish a partnership with NIST, key universities, and industry. By Spring 2008, hold a defining meeting to determine the needs and the direction required to move forward. The initial meeting, led by the Nanomaterials Application Center (NAC) at Texas State Universi- ty-San Marcos, would involve a limited number of key researchers to discuss issues, evaluate progress, identify concerns, and develop a list of critical issues to be investigated. A second meeting within nine months would focus on the research results and the direction of the investigations. Based on these re- sults, a nanomaterials investigative roadmap would be developed for dissemination worldwide. These

results would provide guidance for researchers to address the critical issues. Director of NAC, led the successful investigation of immersion lithography for

    The development of a comprehensive source of information requires two steps. The first involves de- veloping the methodologies for collecting data and developing it into an effective database. The second involves the maintenance of the database and the dissemination of the information. The first needs to involve academic and medical organizations as well as commercial suppliers. Recommendation: Involve industry and academic institutions, like Rice University, UT Health Sciences Center–Houston, Texas State University-San Marcos, Lamar University, NanoTox, Inc., and others in an initial meeting to define the needs and means of proceeding. Other organizations will need to be added as the program develops. The source of funding should include National Institutes of Health, Environmental Protection Agency, and NIST. The development of the eventual information repository will be identified during the course of the initial phase.

    The development of a program to address NANO-SAFETY requires the consideration and evaluation of all the potential known issues and the ability to include other issues as they arise. The program also will require that training programs be put in place to develop the expertise required for handling any nano- technology issues that arise. Recommendations: Numerous steps will be required to develop this effort. The first is the considerations of the work accomplished at major institutions, like Rice University Center for Biological and Environmental Nanotechnology (CBEN).
