What is Nanotechnology?
In this web site, we want you to understand Nanotechnolgy easily. www . What is Nanotechnology .NET will be useful for you.
You could learn what the nanotechnology is. Basicly the nanotechnology is small technology…
Nanotechnology name has came from a plant which is lotus (lotus plant)
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 (millionth of a milimeter)
- It is about the width of five or ten atoms. (about 5-10 atoms)
One day, nanotechnology may 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. How can be repaired holes in ozone layer? Nanotechnology can help us to repair it.
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.
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.
What are the benefits of nanotechnology?
These are benefits of Nanotechnology area. Benefits are will be very useful for humanity.
- Nano Fabrics
- Bio Engineering
- Defence and Security
A mere wisp
A row of 20,000 of these stick figures is more narrow than a human hair.
Researchers are looking at different ways to construct nanorobots the “bottom up” approach uses individual atoms and molecules as building block. This stick figure was created from just 28 carbon monoxide molecules.
Known as “top down” one potential way of building nanomachines is to miniaturize existing machines. There have been some incredible feats, including whis fully working electric motor, just 0.07 inch (1.8 mm) in size.
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)
Nanotechnology on Health
Medicine is the on the most exciting applicaiton areas for nanobots. It may become possible to inject a fleet of nanobots to perfom vital work inside a human body without resorting to surgery. Imagine toothpaste full of nanobots equipped to locate and destroy plaque or nanobots built to clean a diseased blood vessel. (That is the most known information about nanotechnology) Plaque Attack
The diseased section of the blood vessel is covered with a type of plaque containing cholesterol.
We want to show you somethings sizes to learn how small nanotechnology is:
- Ant: 5 milimeters
- Head of a pain: 1-2 milimeters
- Dust mite: 200 micrometers
- Micro Electro Mechanical Devices (Pollen Grain): 10-100 micrometers
- Human Hair: 10-50 micrometers
- Red Blood Cells with White Cells: 2-5 micrometers
- Cellulose Nanofibrils: 20-100 nanometers
- DNA: 1-2 nanometers
- Stacks of Clay Mineral Platelets each Platelet with 1 nanometer thick
- 5 Atoms of Silicon: 1 nanometer
- Carbon Nanotube: 2 nanometer diameter
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.
- Dispersed and contact nanostructures. Example: colloids, aerosols…
- Products incorporating nanostructures. Example: coatings, nanoparticle reinforced composites, nanostructured metals, polymers, ceramics…
- Second generation is Active Nanostructures (2005)
- Bio-active, health effects. Example: Targeted drugs, biodevices…
- First generation is Passive Nanostructures (2000)
- Physico-chemical active. Example: 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. We are in nanotechnology’s fourth generation now)
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
Innovative application. What is nanotechnology benefits?
- Medicine and Drugs (Nanotechnology in PhD)
- Nano Devices
- Optical Engineering
- Computer area
Nanotechnology will be also in computer area.
There will be undead computer viruses or there will be protective soldiers for computer because of nanotechnology.
Hopefully you get the idea of nanotechnology is simplyi basicly what it is. “What is nanotechnology?” if someone asked you, you can answer.
You can write your comments and ask questions about nanotechnology bottom commentors.
