Nanotechnology - Nomenclature
Vydáno dne 24. 11. 2008 (6840 přečtení)

Nanosciences and nanotechnologies mean,in their concept,new approaches to the understanding and utilisation of properties of the mass that critically depend on sizes,which are at the level of nanometres.

Nanoscience is the study of phenomena and manipulation of materials at atomic,molecular and macromolecuar scales,where properties significantly differ from those at larger scale.
Nanotechnologies are the design,characterisation,production and application of structures, devices and systems controlling shape and size at nanometre scale.

The presented definitions were formulated within the preparation of the British study "Nanoscience and Nanotechnologies:Opportunities and Uncertainties" in 2004. It is important to define this interdisciplinary area of science and technology in order to make it different from classic disciplines of science and technology.That is the reason why the words with the prefix of "nano", like, for  example, nanomaterials, nanomedicine,nanobiotechnology,nanoanalytics,nanoelectronics,and a number of others,but also nanochemistry and nanophysics,are often used,even if that can be sometimes misleading.On the other hand, many authors,institutions and companies do not use,in their fields of work done within the nanometre sizes,the prefix nano and that makes the identification of their activities more difficult and may even lead to not precise results of conducted research.
