nanoscale measurement

Nanoscale measurement involves determining dimensions at the nanometer scale, which is one-billionth of a meter. To put this in perspective, a human hair is about 80,000 to 100,000 nanometers wide. This level of measurement is used to study very tiny structures, like atoms and molecules, important in fields like nanotechnology, electronics, and medicine. Specialized tools, such as atomic force microscopes and electron microscopes, are employed to achieve these incredibly precise measurements, enabling scientists to observe and manipulate materials at the atomic and molecular levels.
