Nanotechnology involves the manipulation of materials at the nanoscale, typically between 1 to 100 nanometers (one nanometer is one-billionth of a meter). At this scale, materials often exhibit unique physical, chemical, and biological properties that differ significantly from their bulk counterparts. This allows nanotechnology to offer novel solutions across a wide range of fields.
