- "The earliest, widespread description of nanotechnology referred to the particular technological goal of precisely manipulating atoms and molecules for fabrication of macroscale products, also now referred to as molecular nanotechnology."
- "The National Nanotechnology Initiative defined nanotechnology as the manipulation of matter with at least one dimension sized from 1 to 100 nanometers (nm)."
- "This definition reflects the fact that quantum mechanical effects are important at this quantum-realm scale."
- "Nanotechnology as defined by size is naturally broad, including fields of science as diverse as surface science, organic chemistry, molecular biology, semiconductor physics, energy storage, engineering, microfabrication, and molecular engineering."
- "Nanotechnology may be able to create many new materials and devices with a vast range of applications, such as in nanomedicine, nanoelectronics, biomaterials energy production, and consumer products."
- "nanotechnology raises many of the same issues as any new technology, including concerns about the toxicity and environmental impact of nanomaterials, and their potential effects on global economics, as well as speculation about various doomsday scenarios."
- "These concerns have led to a debate among advocacy groups and governments on whether special regulation of nanotechnology is warranted."
- "Scientists currently debate the future implications of nanotechnology."
