A scientific perspective on the need for and future of nanotechnology
Joseph M. Pickel1, Phillip F. Britt2, and Linda Horton1. (1) Center
for Nanophase
Materials Science, Oak Ridge National Laboratory, 1 Bethel Valley
Road, Oak
Ridge, TN 37831-6494, pickeljm**At_Symbol_Here**ornl.gov, (2) Center for Nanophase
Materials
Sciences and Chemical Science Division, Oak Ridge National
Laboratory, Oak
Ridge, TN 37831-6197
The prefix nano-has been used to describe various new materials and
products as well as new areas of scientific research. While the
implications of this technology have been described in everything
from fiction and commentary to scientific journals, the reality of
the situation is that nanotechnology describes a vast and quickly
growing field of topics that share a common length scale. In this
talk, the presenters-who have a vested interest in the success of
nanotechnology-hope to provide an objective survey of the present
status and future prospects of nanotechnology from a scientific
viewpoint.

A regulatory outlook for "nanosafety"
Kimberly Begley Jeskie, Physical Sciences Directorate, Oak Ridge
National
Laboratory, P.O. Box 2008, MS-6230, Oak Ridge, TN 37831-6230,

A number of Federal and State regulatory agencies, professional
organizations and organizations known for developing consensus
standards are taking an increasing interest in the handling and use
of materials at the nano-scale. This talk will present the status and
outlook of standards and guidance documents that may affect the
future of this field of science.

The interactions of nanoparticles with cells: Is nano neccesarily bad
Miriam Rafailovich, Material Science, SUNY Stony Brook, Stony Brook, NY
11794-2275, miriam.rafailovich**At_Symbol_Here**sunysb.edu, and Nadine Pernodet,
Department
of Materials Science and Engineering, State University of New York at
Stony
Brook, Stony Brook, NY 11794
In order to fully understand whether a nanoparticle has deleterious
effects on human health, it is first neccesary to understant its
interaction with living tissue at the cellular level. Observations of
different classes of nanoparticles reveals that not all nanparticles
are deleterious to cell developement. In fact clays can be benefitial
and we show that it can enhance cell adhesion and protein self
organization, in many cases. Mettalic nanoparticles, on the other
hand can be quite toxic and interfere with normal cell function. Here
the rate of penetration, as well as the mechanism does depend on
particle size. We show that the presence of nanoparticles do not
prevent the cells from dividing. On the other hancd certain basic
functions, such as migration, morphology, and mechanical properties
of both cell and ECM are significantly affected.

Applying control banding in the determination of control measures in
laboratories using nanoparticles
John T. Jankovic, Center for Nanophase Materials Sciences, Oak Ridge
National Laboratory, PO Box 2008 MS 6473, Oak Ridge, TN 37831-6473
Operations staff have been engaged in the development of engineering
and administrative controls for handling materials at the nano-scale
from teh onset of the design phase for the Center for Nanophase
Materials Sciences (CNMS) at the Oak Ridge National Laboratory.
Industrial hygiene staff have developed a control banding strategy
for operations in the facility. This coupled with an industrial
hygiene strategy has positioned CNMS staff and guests with a uniform
understanding of expectations for use of these materials. In this
talk, Mr. Jankovic will provide an overview of the control banding
strategy.
CHAS 28
Development and use of an industrial hygiene sampling method for
nanoparticulates
Randy Ogle, Center for Nanophase Materials Sciences, Oak Ridge National
Laboratory, PO Box 2008 MS 6488, Oak Ridge, TN 37931-6488

Occupational medicine implications of nanoparticulates
Peter Lichty, Health Services, Lawrence Berkeley National Laboratory,
PO Box
2008 MS6488, Oak Ridge, TN 37831-6488
Occupational medicine works hand-in-hand with work place monitoring
and emerging research to better understand the body's response to
interactions with nanoparticles. This talk will focus on the
occupational medicine response to increasing use of nanoparticulates
in the workforce.
CHAS 30
NIOSH: Nanotechnologies safety and health initiatives
Mark Hoover, National Institute for Occupational Safety and Health,
PO Box
2008 MS 6230, Oak Ridge, TN 37831-6230
NIOSH is the leading federal agency conducting research and providing
guidance on the occupational safety adn health implications and
applications of nanotechnology. This research focuses NIOSH's
scientific expertise, and its efforts, on answering the questions
that are essential to understanding these implications and applications:
ï How might workers be exposed to nano-sized particles in teh
manufacturing and industrial use of nanomaterials?
ï How do nanoparticles interact with the body's systems?
ï What effects might nanoparticles have on teh body's systems?
In this talk, Dr. Hoover will discuss key NIOSH safety and health
initiatives related to nanotechnology, including the development of
the Nanoparticle Information Library.
CHAS 31
Challenges of analysis of environmental nanoparticles
Gary Casuccio, R.J. Lee Group, 350 Hochberg Road, Monroeville, PA 15146
As the scientific community has entered the world of nanotechnology,
safety and health professionals are faced with unique challenges in
workplace monitoring. R.J. Lee Group is an innovative materials
characterization company that excels in the analysis of materials
using chemical and microscopy techniques. In this talk, Mr. Casuccio
will discuss emerging analytical techniques and their applications in
worker safety and health.
