What do you think about nanotechnology?

I believe it will take a similar course as electronics and computer technology over the past century, with some of the same benefits as well as consequences.\n\nFirst, don't expect miracles.  Remember people were expecting robots to do and know virtually everything by 2000.  We have progressed a long way, but that was just unrealistic.  I predict nanotechnology within the next 20 years will be comparable to electronics before the discovery of the transistor.\n\nWithin 50 years, I predict something similar to the dot.com boom/bomb.  There will be some very amazing advancements which will spur investment into all kinds of faulty business models.  In the end, a lot of people will lose money but things will settle out at a higher economic level.\n\nAnd as nanotech gets into the hands of common folks, "hackers" will emerge.  I could only make wild guesses on what kind of hacking that would be, but it will be there.  I guarantee that.  Perhaps we will all need to install genetic firewalls to prevent hackers from hijacking our brains! :)

Not yet, but that is the hope for the future. We hope to be able to create nano robots than can go in and repair our cells at the molecular level

It is true that nanotechnology is about creating things smaller than the eye can see, they don't necessarily have to be machines in the traditional sense.\n\nNanotechnology, rather, has become a scientific buzz-word used to describe phenomena on the nanoscale, 0.000000001 meters. What is this small? Well, atoms are generally 1/10th of a nanometer... So if you put a bunch of atoms together, you've got a nanometer.\n\nSome people think of nanotechnology just as making teeny machines (with gears and all), but the field is so much broader than that. Researcher of biological proteins often call their work nanotechnology. Really anything that involves surface interactions or self-assembly is nanotechnology.\n\nAnyway, check out quantum dots. According to Wikipedia, they've made it into Playstations.

Nanotech is indeed real. Have you never seen surveillance cameras the size of a dime, and what about tracking devices about the size of a cigarette lighter?Do you remember how many different components use to be in a regular am radio & tv set? Tubes, capacitors, resistors, coils, etc. are now on a pc circuit board in the form of an integrated circuit about 1"x1/4". The first computer ever devised needed many rooms to house. The laptop now is less than the sise of some wire bound notebooks high school kids carry.

i like scientific american and scientific american mind.  discover is also good, but im personally burnt out on it. ive rec'd it for the last 6 years and over time it just becomes too repetative.  im not sure what a good book for nanotech would be, but for dummies, or for idiots series are usually a good place to start. and sometimes you may be able to get a search result for nanotech in laymans terms.

There are still issues on nanomanufacturing.  If you want to know, nano-electronics are made from nanotransistors.  These nanotransistors are made from carbon nanotubes - they look like sot after a chimney sweep.\n\nThere are already companies involved in nanotechnology.  A few of them are in Massachusetts.  I believe the new generation of optical electronics will have nanotechnology - probably around 2008.

A whole lot of things!  But it starts with research.\n\nI did a project on the bionic eye, which was a computer that linked directly to the visual cortex and a set of glasses.  It was awesome...the person, blind from birth, could see black and white dots, representing locations, but could not judge depth perception.\n\nI suppose biomedical engineering is going to be used for saving people's lives, like with nanotechnology.  In the works are nano computers that can enter the bloodstream and work as super-white blood cells, for example.  Other uses will be for early detection and diagnosis.  As well, there will be treatments for existing diseases, and hopefully a cure for cancer.\n\nOther possible topics for the future of BM Engin. could be the construction and easy use and application of huge bulky machines, like MRI machines.  There is also the idea of radiation treatment either being improved for precision and accuracy, or if that still is too dangerous it could be replaced by "safer" radiation or no radiatino at all.\n\nGood luck!

well science & technology has so many things to talk 'bout ,theres no specific thing.......regarding nuclear technology i feel itz a really good move as it causes no pollution ,renewable ,& will help in consrvation of depletable energy resources......we will benifit greatly 4rm it once itz developed to itz full potential......only problem is regarding safety as itz very dangerous if something goes wrong ........but if we are able to find a way 4r this .......then our energy problems will be solved 4rever

One really easy answer is DNA sequencing. Nanotechnology deals with objects measured in the billionths of a meter. Most say objects less than 100 nanometers. Therefore, although the length of a DNA Strand is way to long to be considered Nanotechnology the individual base pairs fit into nanotechnology perfectly.

The main research for nanotechnology is to make our current technology smaller and more efficent.  However, medical research will be one gigantic step. The innovations that nanotechnology can provide to medicle science is extreme, from minimizing the amount of surgery that is done, to venal and artirial repairs, to healing of wounds and stiching of cuts and fractures.  Some great resources on nanotechnology are listed in the 'sources' section below:

I think it’s a great field to get into. If I was young again I would. With all the new technology becoming available now the things we will see ten years from now will seem like science fiction today. I say go for it!

Nanotechnology is the science of fooling around with materials, albeit at the atomic scale. In their constant endeavor at trying to understand the behavior of materials at the atomic level, scientists when from macro to micro, and now to the nanoscale. Its a known fact that the atomic radii of elements is of the order of a few 10s of angstroms (10 to the -10 meters). So essentially, when we talk of nano technology, we are talking about just a few atoms or molecules - the idea of stacking them together and their interaction with each other and the external environment. The implications of these are enormous. For instance, in the chip industry, as the sizes of the transistors keep shrinking, ultimately they are going to reach a stage where just a couple of atoms are going to be defining a transistor. This is what nanotechnology is all about. \n\nThe idea of "machines" is different at the nano scale. For example, a typical nano-motor wouldn't have shafts, like we're used to seeing. It might just consist of a structure made out of some piezoelectric material which undergoes nano-deformation upon application of a small electric field. Numerous such examples can be cited.\n\nAs for how it is done, one of the methods by which its implemented is through sputtering. Speaking in lay man terms, this is like building walls to the house, brick by brick, except in this case, the bricks are atoms themselves.

Nanotechnology comprises technological developments on the nanometer scale, usually 0.1 to 100 nm (1/1,000 µm, or 1/1,000,000 mm). \nNanotechnology covers a wide range of industries, and therefore the potential benefits are also widespread. Telecommunications and Information technology could benefit in terms of faster computers and advanced data storage.\n\nFor the near-term, critics of nanotechnology point to the potential toxicity of new classes of nanosubstances that could adversely affect the stability of cell membranes or disturb the immune system when inhaled, digested or absorbed through the skin.\ninformation taken from the following link:(also, go there for additional info)

The term "nanotechnology" was defined by Tokyo Science University Professor Norio Taniguchi in a 1974 paper (N. Taniguchi, "On the Basic Concept of 'Nano-Technology'," Proc. Intl. Conf. Prod. Eng. Tokyo, Part II, Japan Society of Precision Engineering, 1974.) as follows: "'Nano-technology' mainly consists of the processing of, separation, consolidation, and deformation of materials by one atom or one molecule."

Nanotechnology is a catch-all phrase for materials and devices that operate at the nanoscale. In the metric system of measurement, “Nano” equals a billionth and therefore a nanometer is one-billionth of a meter. References to nano materials, nanoelectronics, nano devices and nanopowders simply mean the material or activity can be measured in nanometers. To appreciate the size, a human red blood cell is over 2,000 nanometers long, virtually outside the nanoscale range!\n \n  \n \nRecently, government and private institutions have devoted substantial research into finding potential valuable uses at this scale, as discussed below.
