Nanotechnology
Nanotechnology is a relatively new science defined by use of engineered particles with dimensions in the 1-100 nanometer (nm) range. As a reference, the width of a carbon atom is 1 nm. The list of engineered nanomaterial particles being used in research and consumer products is growing, and includes buckyballs, nanotubes, quantum dots and nanogels; each having unique characteristics that give them properties existing materials lack.
What are the health effects of these particles on the human body if they are inhaled, ingested or contact the skin? How does one store and dispose of a nanomaterial waste? Currently, different organizations, including the National Institute of Occupational Safety and Health (NIOSH), are researching the health and disposal aspects of nanomaterials.
Initial animal studies indicate that inhaled nanomaterials can cross the lung/blood barrier and deposit in internal organs. Skin penetration is another exposure route for nanoparticles. More research is needed on nanomaterials and ingestion. Because nanomaterial toxicity is not fully understood, nanomaterials must be treated with a high level of control.
