What Does Miniaturized Mean in Nanotechnology?
Miniaturized refers to the process of scaling down devices and systems to extremely small dimensions, often at the nanoscale, where unique physical and chemical properties emerge. In the context of
Nanotechnology, this involves manipulating materials on an atomic or molecular level to create structures and devices with dimensions typically less than 100 nanometers.
How is Miniaturization Achieved?
Miniaturization is achieved through various techniques including
top-down fabrication and
bottom-up fabrication. Top-down methods involve reducing the size of bulk materials to the nanoscale through processes like lithography and etching. Bottom-up methods, on the other hand, build structures atom-by-atom or molecule-by-molecule using techniques such as
self-assembly and chemical vapor deposition.
