About Nanotechnology
“Nanotechnology” is an applied technology that deals with the manipulation, construction, synthesis of materials or devices at the atomic level. Molecules or fragments as small as 1 to 100 nm result in materials or devices that have new functions and special properties in terms of physical, chemical and biological aspects having advantages for users and increasing economic value.
3 Elements of Nanotechnology
- Small size in the scale of 1 – 100 nm.
- Accurate and controllable.
- Create new functions or properties
How small is… Nano level?
Small ant is about 5 mm in size, pin head is about 1-2 mm. However, in the case of hair, the diameter is approximately 10-50 micrometers, followed by dust (about 10-20 micrometers) and red blood cells (about 6-8 micrometers). The nanometer level is even smaller, such as, the circular diameter formed by the arrangement of 48 iron atoms on copper is about 14 nm, followed by carbon nanotubes (about 2 nm), and fullerene molecules (about 1 nm), respectively.
