Nanoscale imaging refers to the technology and techniques used to visualize and study materials or structures at the nanometer scale, which is one billionth of a meter. This field is crucial in understanding and manipulating materials at the atomic and molecular levels, as well as for the development of advanced nanotechnologies. Nanoscale imaging techniques include scanning electron microscopy, atomic force microscopy, transmission electron microscopy, and scanning tunneling microscopy, among others. These techniques provide researchers with the ability to visualize and analyze materials with unprecedented detail and resolution, enabling advancements in fields such as materials science, biology, and nanotechnology.
