Definition of nanometer in English:



(British nanometre)
  • A metric unit of length equal to one billionth of a meter.

    ‘These things are measured in nanometres, with a nanometre being a millionth of a millimetre, or about as far as a fingernail grows in a second.’
    • ‘The grids comprise carbon nanotubes - long, hollow cylinders of pure carbon a few millionths of a millimetre across and several thousand nanometres long.’
    • ‘Nanotechnology is used to study the fabrication and manipulation of structures that range in size from one hundred nanometres to a single nanometre (or a billionth of a metre).’
    • ‘The Casimir effect could also play a role in accurate force measurements between the nanometre and micrometre scales.’
    • ‘This figure was used to convert subsequent contour measurements from nanometers to kilobases.’
    • ‘Nanomagnets can measure anything from just under a micron to a few nanometres in size, and have applications that range from medical imaging and drug delivery to sensors and computing.’
    • ‘The data are stored in tiny sheets of plastic polymer film as tiny indentations just 10 nanometers, or millionths of a millimeter, in diameter.’
    • ‘Amorphous, polycrystalline, or epitaxial films can be made with thicknesses from 10 nanometers to hundreds of nanometers or thicker.’
    • ‘Then he formed fibers with diameters of between 300 nanometers and 500 nanometers and began using them to fabricate scaffolds on which to grow human cells.’
    • ‘Each ring - composed of polymer chains abandoned as the solvent receded - is several nanometers high and several microns wide.’
    • ‘The mineral forms within a protein matrix as fibrous structures about 50 nanometers wide and 500 nanometers long.’
    • ‘In fact, it can exhibit ordered structures with length scales ranging from micrometers to nanometers.’
    • ‘That distance varies from a few hundred nanometers to a few micrometers, depending on atom velocity.’
    • ‘It looks similar to the CD-ROM on the left, but the scale is in nanometers instead of micrometers.’
    • ‘In addition, he says, the new hydrogels have well-ordered networks of pores on both the nanometer and micrometer scales.’
    • ‘Colloidal dispersions have particle sizes in the 1.0 nanometer to 0.50 micrometer range.’
    • ‘A nanometer is one-thousandth of a micron, which is one millionth of a meter.’
    • ‘As we approach dimensions of one billionth of a metre the nanometre scale it is now appropriate to talk about nanoelectronics rather than microelectronics.’
    • ‘Transistors, which next year will contain features measuring 45 nanometres, or billionths of a metre, have become so small that they leak substantial amounts of electricity.’
    • ‘The width of the dot above this letter i is approximately 1 million nanometers.’
