Nanotechnology: Nanoscale Particles A Health Hazard?

securitas writes "Before you start dreaming of all the benefits nanotechnology will bring you, think about the health hazards. Over two dozen studies that date back to 1984 indicate that nanoscale materials are toxic because their size allows them to be easily ingested, inhaled or absorbed through the skin. Proponents of nanotech dismiss the meta-study as nonsense, while the authors suggest a moratorium on nanotech development until further health research is completed."
