wat is nanotechnology?

Question

pls do give its applications and details.HOw is useful in day to day life???

Answer 1

Nanotechnology is the study and production of machines and other things on the nano scale (1 nanometre = 1 billionth of a metre). With today's technology we can build things atom by atom into just about any shape we want.

This picture above was taken with an electron microscope. To put it into perspective, the each gear tooth you can see is smaller than a red human blood cell. If you were to look at a speck of dust it would be an enormous nanobot. The main applications that it is being studied today apply to medicine. Carbon nanotubes for instance are now in at the stage of human trials to help people with diabeties. The nanotube pictured below is made up entirely of carbon. Each of these dots is a carbon atom.

The nanotube slowly releases insulin into the blood stream. This would mean that a diabetic would only have to swallow one of these every week or so as opposed to getting daily injections. There has also been advancement in the area of medicine delivery for cancer treatment by creating robots that run on your body heat and deliver drugs to the area that needs them. This means that you can use much smaller doses of what are essentially toxic chemicals.

People have also grown Neurones along what is called a nanosheet which is made up of carbon fibres. Hopefully in the next 10 to 20 years we may be able to cure people who have had their backs broken and spine severed.

This picture is of what are known as nanoflowers. These crystals can be engineered to react to just about any subatance you like. They are being experimented on to test for cancer as cancer makes your body produce certain chemicals. Also they can be used for alcohol, marajuana and many types of anphetimines. This is currently being trialled in Australia.

Nano technology is a relitivley new field of research however the potential here is nearly limitless. It is the next step forward in scientific evolution.

Answer 2

>scale one-billionth (nano) of an inch?

This is essentially correct. It is about very small machines, not just of silicon but of almost any material depending on purpose. Not all nano materials are machines or robots, some are just particles that display interesting and useful properties.

It has applications in materials science, in coatings and alloys for example.

It has applications in medicine as mentoined.

I has applications in pretty much every field of technology. Smaller things take less energy to do similar functions, and can address smaller increments of things and thus yield less waste. Smaller particles allow for better filters, treatments for various pollutants not currently treatable.

The list is really far too extensive to type on here.

You should read the book "Engines of Creation" by Drexler for some very interesting considerations of the technology and it's implications and applications.

Answer 3

Nanotechnology is the engineering of functional systems at the molecular scale. This covers both current work & concepts that r more advanced.
In its original sense, nanotechnology refers to the projected ability to construct items from the bottom up, using techniques & tools being developed today to make complete, high performance products.

In addition, nanotechnology deals with devices typically less than 100 nanometers in size, is expected to make a significant contribution to the fields of computer storage, semiconductors, biotechnology, manufacturing & energy.

Envisioned r all kinds of amazing products, including extraordinarily tiny computers that r very powerful, building materials that r withstand earthquakes, advanced system for drug delivery & custom-tailored pharmecuticals as well as the elimination of invasive surgery , b'coz repairs can be made from within body.

Answer 4

From what I know it concerns the microscopic robots and machines.Maybe not microscopic though, but anyway science reached the point where in surgical interventions the traditional operation tools are replaced with tiny machines that can do all the job without all the blood...This is only one aspect of the nanotechnology, there are many other domains that use nanotech..

Answer 5

Do it for a year

Answer 6

Basicly it's the technology dealing with VERY SMALL things. In the science fiction movies (like star trek) they have nanobots that are little machines so small you need an electron microscope to see them. Because of their small size, they can preform tiny tasks, like surgery on individual cells in the body, or working with tiny computer components.
Today we can't do that, but I think that that's our goal.

Answer 7

nano means small. application is in all aspects of life and aim is to make smaller and smaller gadgets so that we can do away with bulky gadgets.
It is not limited to computers but covers a very wide range of applications.

Answer 8

all i know is its cutting edge technology that structurly engineers matter (silicone) on a scale one-billionth (nano) of an inch?
the future will be fiber-optics though silicone is likely enter picotechnology befor
