nanotechnology

(nă″nō-tĕk-nŏl′ŏ-jē) [L. nanus, dwarf, + Gr. technē, art, + logos, word, reason]
The scientific study and engineering of chemical or biological objects measuring between 1 and 1000 nanometers. Objects this small are about the size of atoms or small molecules. “Wet” nanotechnology is the manipulation of organic or biological compounds in solution. “Dry” nanotechnology is the engineering of objects on silicon or carbon surfaces, such as those used in computing.

nanotechnology

The application of the science of manipulation at an atomic level. The practical applications of the ability to move single atoms so as to construct molecules, materials, structures and even functioning machines at an atomic level. Nanotechnology is currently at a germinal stage but is expected to have extensive applications in medicine. See also MAGNETIC NANOPARTICLES.

FDA regulation / The FDA is a key regulator of nanotechnology. And yet the agency has acknowledged that it cannot adequately regulate (medical) products of "new sciences" such as nanotechnology.
Artificial mechanical red blood cells will be expected to be able to deliver more oxygen to the tissues than natural red blood cells and artificial mechanical white blood cells will be able to destroy microbiologic pathogens.3 Surgeons are always in search of minimally invasive techniques of surgery and this can be achieved successfully by nanotechnology. Application of nanotechnology in surgery is mostly at cellular level where a human hand cannot perform precisely.
While the use of nanotechnology in food packaging increases freshness, protects from moisture and bacteria, and provides spoliation sensors, there are health and environmental concerns that nanoparticles will migrate into food or the environment via landfills.
(2010) challenged this: they looked at food nanotechnology in the news over a decade by analysing 1971 US news articles published in the period 1999-2009, examining them for dominant content themes (including consumer issues such as packaging, and sector issues such as agriculture) and conceptual themes (risks, benefits, uncertainty).
This academic year (2013-14), the college is offering Fundamentals of Nanotechnology I, which covers the basic application of this field, and Fundamentals of Nanotechnology II, which concentrates on such topics as how physical properties relates to size, quantum mechanics, and various methods that atoms and molecules bond.
