Nanotechnology deals with materials and devices on the nanoscale, which typically ranges from 1 to 100 nanometers (nm). To put this into perspective, a nanometer is one-billionth of a meter, which is approximately 100,000 times smaller than the diameter of a human hair. This size range is crucial because materials often exhibit unique physical, chemical, and biological properties at the nanoscale that are different from their bulk counterparts.
