Nanotechnology Research Center

Program Description

The Nanotechnology Research Center (NTRC) conducts research to better understand the effects of engineered nanomaterials on human health and methods to control or eliminate exposures. Nanomaterials are extremely small particles (with at least one dimension between 1 and 100 nanometers) purposefully designed to have certain new or unique characteristics, like strength or elasticity, needed to make advanced materials and products.

NIOSH is the leading federal agency conducting research and providing guidance on the occupational safety and health implications and applications of nanotechnology. Given the rapid growth and global reach of nanotechnology, NIOSH established the NTRC in 2004 to identify critical issues, create a strategic plan for investigating these issues, coordinate the NIOSH research effort, develop research partnerships, and disseminate information gained. The NTRC is comprised of nanotechnology-related activities and projects consisting of and supported by a diverse group of scientists from various NIOSH divisions and laboratories.

NTRC works with partners in industry, labor, trade associations, professional organizations, other federal agencies, and academia. The NTRC focuses on these areas:

• Increasing understanding of hazards and related health risks to workers who make and use nanomaterials.
• Preventing occupational exposures to nanomaterials through understanding control technologies and protective technologies.

Much research is still needed to understand the impact of nanotechnology on health, and to determine appropriate exposure monitoring and control strategies. At this time, the limited evidence available suggests caution when potential exposures to free–unbound nanoparticles may occur.
