Question

What is nanotechnology? is it good or bad?

Answer 1

Nanotechnology:

Manipulation of atoms, molecules, and materials to form structures on the scale of nanometres (billionths of a metre). These nanostructures typically exhibit new properties or behaviours due to quantum mechanics. In 1959 Richard Feynman first pointed out some potential quantum benefits of miniaturization. A major advancement was the invention of molecular-beam epitaxy by Alfred Cho and John Arthur at Bell Laboratories in 1968 and its development in the 1970s, which enabled the controlled deposition of single atomic layers. Scientists have made some progress at building devices, including computer components, at nanoscales. Faster progress has occurred in the incorporation of nanomaterials in other products, such as stain-resistant coatings for clothes and invisible sunscreens.

More About Nanotachnology:

For the scientist, advancing the sum total of human knowledge has long been the driving force behind discovery, from the gentleman scientists of the 17th and 18th centuries to our current academic infrastructure. Nanotechnology is at a very early stage in our attempts to understand the world around us, and will provide inspiration and drive for many generations of scientists.

For business, nanotechnology is no different from any other technology: it will be judged on its ability to make money. This may be in the lowering of production costs by, for example, the use of more efficient or more selective catalysts in the chemicals industry, by developing new products such as novel drug delivery mechanisms or stain resistant clothing, or the creation of entirely new markets, as the understanding of polymers did for the multi-billion euro plastics industry.

Politically, it can be argued that fear is the primary motivation. The US has opened up a commanding lead in terms of economic growth, despite recent setbacks, as a result if the growth and adoption of information technology. Of equal significance is the lead in military technology as demonstrated by the use of unmanned drones for both surveillance and assault in recent conflicts. Nanotechnology promises far more significant economic, military and cultural changes than those created by the internet, and with technology advancing so fast, and development and adoption cycles becoming shorter, playing catch-up will not be an option for governments who are not already taking action.

Maybe the greatest short term benefit of nanotechnology is in bringing together the disparate sciences, physical and biological, who due to the nature of education often have had no contact since high school. Rather than nanosubmarines or killer nanobots, the greatest legacy of nanotechnology may well prove to be the unification of scientific disciplines and the resultant ability of scientists, when faced with a problem, to call on the resources of the whole of science, not just of one discipline

Answer 2

Nanotechnology is the engineering of functional systems at the molecular scale...it is good or bad is all upto you, yaa but it has a lot of scope in the future..

Answer 3

Nanotechnology is a good thing. If you know anything about computers, think of it as the next huge advancement in electronics/medical technology. Nanotechnology has so many potential uses I couldn't even begin to cover them here, just know that in the future we'll be capable of utterly AMAZING things because of nanotechnology.

Answer 4

A technology that creates small materials at the scale of molecules by manipulating single atoms. The name nano comes from the size of molecules which is measured in nanometers - or one billionth of a meter (0.000000001 meter). The dimension of single atoms is ten fold smaller.

Answer 5

the technology of producing very fine materials for different purposes, cause different properties,i work in factory (nanotechnology ) we produce very fine powder<40 micron

which is used in paper and pharmasotical industeries.this one purpose of nanotechnology ,its good

Answer 6

I don't know nanotechnology

  but  I know it is good

Answer 7

Nanotechnology is the engineering of functional systems at the molecular scale.

It has loads of applications in every imaginable field - communication, medicine, tech - you name it!

The most striking feature is the fact that it is of nanoscale : imagine a tiny machine like thing entering into your body and taking pictures of all organs and things [that's rather a crude way of putting it :D] and then verifying if everything's functioning normally .....

As with every new technology, this, too, has got its own advantages and disadvantages - but hey, that's how life is.

Let's look at the bright side and hope for the best! After all, it's us who make up the world!
