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.

A nanogear

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.

Bottom up

A mere wisp

A row of 20,000 of these stick figures is more narrow than a human hair.

Top Down

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)

Plaque Attack

The diseased section of the blood vessel is covered with a type of plaque containing cholesterol.

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)

Waste Away

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.

Micro cleaner

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

Innovative Application. What is nanotechnology benefits?

• Energy
• Medicine and Drugs
• Nanobio-technology
• Nano Devices
• Optical Engineering

Nanotechnology will be computer area.

There will be undead computer viruses or there will be protective soldiers for computer.
