Devising appropriate oversight for nanotechnology is a challenge. The field spans many scientific disciplines and product areas, capitalizing on the unusual properties and capabilities of material at the atomic scale. The critical feature of nanotechnology is not only the size at which manufacture occurs (˜1-100 nanometers), but also the ability to control and manipulate the novel chemical, physical, and mechanical properties that emerge at this scale, including increased conductivity, optical properties, and reactivity. As nano-products enter the research and development (R&D) phase, hit the market, and enter consumer households, debate has emerged on oversight approaches. Regulators, manufacturers, and commentators are considering whether existing oversight systems are sufficient, those oversight systems need adjustment, or new oversight systems are needed.
