Nanotechnology

Rare card · No. 68151

Nanotechnology is the manipulation of matter with at least one dimension size measuring between 1 to 100 nanometers (nm). At this scale, commonly known as the nanoscale, surface area and quantum mechanical effects become important in describing the properties of matter. This definition of nanotechnology includes all types of research and technologies that deal with these distinctive properties. The plural form “nanotechnologies” is also commonly used, as is the term “nanoscale technologies,” to refer to research and applications whose defining characteristic is their scale. An earlier understanding of nanotechnology referred to the particular technological goal of precisely manipulating atoms and molecules for the fabrication of macroscale products, now referred to as molecular nanotechnology. A near-synonym of "nanotechnology" is nanoscience (i.e., nanophysics, nanochemistry, nanobiology and nanoinformatics); however, the term "nanoscience" emphasizes the pure science aspects of the field...
