J. Jordan Bouchard 04/13/2008 CHEN 1000 Nanotechnology “Everything we see around us is made of atoms, the tiny elemental building blocks of matter. From stone, to copper, to bronze, iron, steel, and now silicon, the major technological ages of humankind have been defined by what these atoms can do in huge aggregates, trillions upon trillions of atoms at a time, modeled, shaped, and refined as macroscopic objects. Even in our vaunted microelectronics of 1999, in our highest-tech siliconcomputer chip the smallest feature is a mountain compared to size of a single atom. The resultant technology of our 20 th century is fantastic, but it pales when compared to what will be possible when we learn to build things at the ultimate level of control, one atom at a time.” - Richard E. Smalley Nanotechnology is any technology which exploits phenomena and structures that can only occur at the nanometer scale, which is the scale of single atoms and small molecules. The United States' National Science and Technology Council states "The essence of nanotechnology is the ability to work at the molecular level, atom by atom, to create large structures with fundamentally new molecular organization. The aim is to exploit these properties by gaining control of structures and devices at atomic, molecular, and supramolecular levels and learn to efficiently manufacture and use these devices”. “Nanoscience and nanotechnology are an extension of the field of materials science , and materials science departments at universities

around the world in conjunction with physics, mechanical engineering, bioengineering, and chemical engineering departments are leading the breakthroughs in nanotechnology” (Mansoori, 2005). The first mention of some of the distinguishing concepts in nanotechnology (but predating use of that name) was in "There's Plenty of Room at the Bottom", a talk given by physicist Richard Feynman at an American Physical Society meeting at Caltech on December 29, 1959. Feynman described a process by which the ability to manipulate individual atoms and molecules
