Nanotechnology is the design, characterization, production and application of structures, devices and systems by controlling shape and size at the nanoscale. Eight to ten atoms span one nanometer (nm). The human hair is approximately 70,000 to 80,000 nm thick.
Nanotechnology should really be called “nanotechnologies”: There is no single field of nanotechnology. The term broadly refers to such fields as biology, physics or chemistry, any scientific field, or a combination thereof, that deals with the deliberate and controlled manufacturing of nanostructures.The United States' National Nanotechnology Initiative website defines it as follows: "Nanotechnology is the understanding and control of matter at dimensions of roughly 1 to 100 nanometers, where unique phenomena enable novel applications."
Nanoscience is the study of phenomena and manipulation of material at the nanoscale, in essence an extension of existing sciences into the nanoscale. Nanoscience is the world of atoms, molecules, macromolecules, quantum dots, and macromolecular assemblies, and is dominated by surface effects such as Van der Waals force attraction, hydrogen bonding, electronic charge, ionic bonding, covalent bonding, hydrophobicity, hydrophilicity, and quantum mechanical tunneling, to the virtual exclusion of macro-scale effects such as turbulence and inertia. For example, the vastly increased ratio of surface area to volume opens new possibilities in surface-based science, such as catalysis.
