Exponential Proliferation

Nanotechnology not only creates the possibility of many high quality products at very low cost, but introduces the possibility for new nanoplants the same low cost and speed. This unique (outside of biology, that is) the ability to reproduce its own means of production Therefore, nanotechnology is considered a technology exponentially. It represents a production System will be capable of manufacturing systems can build factories to make more Mills quick, inexpensive and clean. The means of production will be able to play exponentially, so that in a few weeks, a few dollars nanofactories, could be envisaged. This is a revolutionary transformation, powerful and potentially very dangerous of technology.

Multi-Use Technology

Like electricity or computers before it, nanotechnology will significantly improve efficiency in providing almost all aspects of life. But as a general-purpose technology is dual-use that is, he will make many commercial uses and has many military applications much more powerful weapons and tools of surveillance. Thus, it is not only beautiful Benefits for mankind, but also significant risks.

A key understanding of nanotechnology is that not only offer better products, but Production process significantly improved. A computer can make copies of data files, in essence, as many copies as you with little or no cost. There may be a matter of time until the Construction is as cheap as the copying of files. This is the true meaning of Nanotechnology, and why it is sometimes referred to as the next industrial revolution seen.

Common-Purpose Technology

Nanotechnology is sometimes referred to as a technology for general purposes. This is because in its advanced form, which will have a significant impact on almost all industries and all sectors of society. He built a better, more sustainable products cleaner, safer and smarter for the home, communications, medicine, transport, agriculture and industry in general.

Mixing Definitions

Unfortunately understand conflicting definitions of nanotechnology and the blurring of distinctions between the many different areas, the commitment to the politics of difference and development have complicated sensory effect.

The risks of nanotechnology, today (the toxicity of nanoparticles, etc.). It can not be treated as a threat of long-term molecular manufacturing (economic disruption, unstable arms race, etc. ..) CE 'an error in putting together a pot to throw in the review of policies, each important to address, but have different problems and require different solutions. As the term nanotechnology is used today, usually in a large collection of mostly disconnected fields. Virtually everything that can be described as nanotechnology small and interesting. Much of it is harmless. For the rest, much of the damage limited and the quality is unknown. But, as we shall see, molecular manufacturing will bring and unknown risks and new classes of problems.

What does nanotechnologies future hold?

It, the exact date is difficult to estimate the actual different nanotechnologies. However, in the future, nanotechnology may have an impact on many areas of life is possible.

Nano technology in the short term is smaller, faster computers and more sharply, more efficient electronic displays may occur. They can reduce the weight of paint to put the aircraft in the nanoparticles, and lower fuel consumption will reduce the total weight is used. Nanoparticles can also help protect the environment clean. The researchers examined hazardous chemicals nanoparticles soil and groundwater ability to turn into dangerous compounds found.

Important applications in medicine are expected in the long run. Nanoparticles to deliver drugs to specific parts of the body can be used. They can be used to make, lightweight, durable implants such as heart valves and hip replacements. We monitored blood pressure and heart rate and recognition of hazardous chemicals and the environment can see the manufacturer can develop intelligent clothing.

Long-term potential to create energy-efficient applications nano-membrane water treatment process, take any more high-performance lubricants and machinery, including engineering.

How nanomaterials are made of ?

Nanomaterials natural or artificial. For example, nanoparticles of natural plants, algae, and produced by volcanic activity. Year, thousands of them, was prepared by cooking the vehicle exhaust and combustion products, and more lately. Some repair proteins in cells of the body such as muscle flexion, and nanometer-scale control of something. We can create a variety of different possibilities Nanomaterials. Some of their components can be installed Nanomaterials. Carbon part may, for example, self-assembling nano-tubes in this way. Another approach in the production of computer chips, the material will be etched in large pieces Nanomaterials used. Increasingly, these two methods to meet, leading the new production techniques that interesting.

Powerful microscope, researchers only for atoms and molecules look more closely, but was developed to get them and go to the form of basic nanostructures. Molecule by molecule will be built few Nanomaterials means. For example, this technique is used to manipulate atoms to clarify the IBM logo. However, these techniques are too expensive and not suitable for industrial processes.

IBM logo, the spelling in the context of Xenon atoms showed nanometer length scale. Each letter from top to bottom is about 5 miles. Image by permission of IBM Research, Almaden Research Center can be reproduced. Unauthorized use is strictly prohibited.

How are nanotechnologies being used?

Several nanotechnologies for hundreds of years, for example, gold and silver nano-pigment as stained glass windows from the 10th Century used identified.

Many chemical and nano-chemical process. Chemists, a large molecule formed in the polymer nano-size components for years. Has a nano-computer chips, which feature high-etched surface, and the technology allows a computer can be made smaller and faster during the last thirty years.

Recently, researchers have produced nano-scale wires and pipes. Nanowires, extraordinary, there are electronic and magnetic properties of the optical computer data storage, so the hope would be useful. Carbon nanotubes much stronger and lighter than steel, new materials may result.

Nanoparticles - tiny particles that private property - also noted some areas of the application. Nano titanium dioxide sunscreen and cosmetics included. These small particles, and transparent skin that absorbs and reflects UV rays.

Cosmetics, where you can move freely use it against the surface layers of nanoparticles, to give them new features are optional. Thus, the rain and remained stable for laminated glass, it breaks down for example, titanium dioxide, small particles of dirt away, to solve the self-cleaning window glass - glass, water and sunlight can be used.
