Nanoprinting involves the use of specialized tools to transfer intricate designs onto a substrate. In nanoimprint lithography, for example, a mold with nanoscale features is pressed into a thin film of polymer on a substrate. The polymer is then cured, and the mold is removed, leaving behind a nanostructured pattern. Other methods, such as dip-pen nanolithography, use atomic force microscope tips to deposit materials at specific locations with nanometer precision.
