Nanotechnology and safety: truths and misconceptions

Dispelling misconceptions about nanoelectronics research

When it comes to one specific area of nanotechnology — nanoelectronics — the more pressing health and safety concerns do not realistically apply, says Wolfgang Porod, Ph.D., director of Notre Dame's Center for Nano Science and Technology. Nanoelectronics involve electronic components on the nanoscale level.

"Most of the health concerns related to nanotechnology are about nanoparticles, which may enter the environment via the air or water and be inhaled or ingested," says Porod. "Yet our work in nanoelectronics is very different because these electronic components do not become airborne. Instead, they are fabricated on a semiconductor chip."
