Overview

What is Nanotechnology?

Nanotechnology refers to engineered structures, devices, and systems. It is the manipulation of matter on a near-atomic scale to produce new structures, materials and devices. Nanomaterials have a length scale between 1 and 100 nanometers. At this size, materials begin to exhibit unique properties that affect physical, chemical, and biological behavior. Researching, developing, and utilizing these properties is at the heart of new technology.

Nanotechnology promises scientific advancement in many sectors such as

  • Medicine
  • Consumer products
  • Energy
  • Materials
  • Manufacturing

What are the Risks to Workers?

Workers within nanotechnology-related industries may be exposed to uniquely engineered materials. This includes materials with new sizes, shapes, and physical and chemical properties. Occupational health risks associated with manufacturing and using nanomaterials are not yet clearly understood. More research is 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.

What is Known?

Studies have indicated that low solubility nanoparticles are more toxic than larger particles on a mass for mass basis. Particle surface area and surface chemistry are strong indicators for observed responses in cell cultures and animals. Studies suggests that some nanoparticles can move from the respiratory system to other organs. Research is continuing to understand how these unique properties may lead to specific health effects.

Nanotechnology Research Center

NIOSH conducts research and provides guidance on the occupational safety and health implications and applications of advanced materials and nanotechnology through its Nanotechnology Research Center.
