Nanoscale manipulation refers to the techniques used to control and arrange materials at the nanoscale, typically between 1 to 100 nanometers. This scale is crucial because materials often exhibit unique properties at this size, which can be harnessed for various applications, including electronics, medicine, and materials science. Techniques such as scanning tunneling microscopy and atomic force microscopy allow scientists to visualize and manipulate individual atoms and molecules. The ability to manipulate materials at this scale opens up new possibilities for innovation. For instance, in nanotechnology, researchers can create more efficient solar cells, targeted drug delivery systems, and stronger materials. By understanding and controlling interactions at the nanoscale, advancements in technology and medicine can be significantly accelerated.
