nanotechnology, n.|ˌnænəʊtɛkˈnɒlədʒɪ|
[f. nano- + technology n.]
The branch of technology that deals with dimensions and tolerances of 0.1 to 100 nanometres, or (gen.) with the manipulation of individual atoms and molecules.
1974N. Taniguchi in Proc. Internat. Conf. Production Engin. ii. 18/1 From the emergent needs based on these industrial requirements, the system of ultra fine finishing or ‘Nano-technology’ has been introduced. The usual precision finishing technology has aimed to get the preciseness and fineness of 1 µm, i.e. 10-6m in length, hence it says ‘micro-technology’, not so accurate in meaning. Consequently, in contrast, the finishing technology aimed to get the preciseness and fineness of 1nm would be called ‘Nano-technology’. Ibid. 22/1 In the ‘Nano-technology’ in materials processing, the processing by one atom or one molecule should be fully utilized. 1986K. E. Drexler Engines of Creation i. 11 As nanotechnology moves beyond reliance on proteins, it will grow more ordinary from an engineer's point of view. 1988New Scientist 24 Mar. 71/3 Nanotechnology differs from microtechnology, being based on molecular manipulation rather than the miniaturisation of bulk processes. 1992Times Higher Educ. Suppl. 27 Mar. 50/1 (Advt.), Our Electronics Research and Development Centre (ERDC) is managing a LINK Nanotechnology Programme project involving the application of silicon micromachined devices to blood cell analysis.
Hence ˌnanotechnoˈlogical a.; nanotechˈnologist n., an expert in or student of nanotechnology.
1986Washington Post 21 Dec. d3/4 These developments still involve the manipulation of huge numbers of atoms, and are crude compared with the manipulations the nanotechnologists hope to achieve—one atom at a time. 1989Sunday Times 17 Sept. d5/6 The idea resembles work towards nanotechnological machines—a vision of tiny molecular kits for fabricating materials, molecule by molecule. 1993Nature 11 Mar. 123/3 Microlithography is ignored,..and astonishingly we are told that the nanotechnological computer will be mechanical, like a Lilliputian version of Babbage's difference engine. |
