What is nanotechnology? You could learn what the nanotechnology is.
Basicly the nanotechnology is small technology…
Technology is shrinking fast. Computing technology that would have filled a warehouse 30 years ago can now be squeezed onto a chip a fraction of the size of your thumbnail.
The very smallest scale of engineering is called nanotechnology. A nanometer is a billionth of a meter, about the width of ten atoms.
Nanotechnology may, one day, be capable nanorobotics, nanorobots or nanobots. Working at an almost atomic level, nanobots could build complex items cheaply and repair clothes, equipment and even people without being noticed.
They could also be used to rid the atmosphere of pollution and to repair holes in the ozone layer.
Machines made from individual atoms, like this differential gear, have reached the computer modelling stage, but have not yet been built.
For nanotechnology to work, they would need to be made in huge numbers. Scientists are looking to nature for ideas on how nanobots.
May be self-replicating, like plant and animal cells than a human hair.
Each ball represents one atom. The whole gear measures just a few nanometers in diameter.
May the force be with you
This manipulator is a big step toward an assember that can built nanobots from atoms. It uses an atomic force microscope, together with sopihisticated handling tools to manipulate minute particles.

A mere wisp
A row of 20,000 of these stick figures is more narrow than a human hair.
Putting it in context
A plankton skeleton, just 0.008 in (0.2 mm) across, sits on one of the engine’s cogs, measuring 0.02 in (0.5 mm)
The diseased section of the blood vessel is covered with a type of plaque containing cholesterol.
We want to show you some photos about nanotechnology.

What are applications of nanotechnology? Uses of Nanotechnology?
Nanotechnology will be on health area.
There is a nanotechnology item with red blood cells in vein or artery on this photo. It work to repairs the problems about human body.
Nanotechnology development has four generations.
a. Dispersed and contact nanostructures. Example: colloids, aerosols…
b. Products incorporating nanostructures. Example: coatings, nanoparticle reinforced composites, nanostructured metals, polymers, ceramics…
- Second generation is Active Nanostructures (2005)
a. Bio-active, health effects. Example: Targeted drugs, biodevices…
- First generation is Passive Nanostructures (2000)
b. Physico-chemical active. Examle: 3D transistors, amplifiers, actuators, adaptive structures…
Example: 3D networking and new hierarchical architectures, robotics, evolutionary…
Example: Molecular devices “by design”, atomic design, emerging functions…
P.S: Nanotechnology can be very useful for human generations or can’t be…
- Third Generation is Systems of Nanosystems (2010)
- Fourth Generation is Molecular Nanosystems (2015-2020)
The nanobot would either remain inside the blood system, constantly performing its task or it would be programmed to biodegrade safely, carrying the waste plaque out of the human body.
Saw “n” scrape
An incredibly small rotary saw would scrape the plaque free from the blood vessel wall.
A vacuum hose would stuck up the waste plaque for safe storage inside the nanobot.
The Challenge : Fabricate and combine nanoscale building blocks to make useful device, e.g a photosynthetic renction center with integral semiconductor strage.
Benefits of Nanotechnology
