\nNanotechnology is broadly defined as the understanding, manipulation, and control of matter at the nanoscale, typically ranging from approximately 1 to 100 nanometers (nm).
\n<\/section>\n
\nA nanometer (nm) is one billionth of a meter (10\u207b\u2079 m). The 1 to 100 nm range is considered the nanoscale because materials within this size range often exhibit unique physical, chemical, and biological properties that differ significantly from their bulk counterparts. This is due to quantum mechanical effects and a large surface area-to-volume ratio.
\n<\/section>\n
\nDifferent units of measurement relate to nanometers as follows: 1 \u00c5ngstrom (\u00c5) = 0.1 nm, 1 micrometer (\u00b5m) = 1000 nm, 1 millimeter (mm) = 1,000,000 nm. Option A (1 \u00c5 \u2013 10 nm) is a narrower range within the nanoscale. Options C and D represent the microscale and millimeter scale, respectively, which are much larger than the nanoscale.
