I found a source for the surgery section, but I'm not so knowledgeable in marking citations, so perhaps someone else can do it for me. It's http://www.nanomedicinecenter.com/article/surgery-and-nanomedicine/. It looks like it was pretty much copied... ZAD-Man (talk) 05:40, 9 August 2011 (UTC)
The entire nanorobot section is basically science fiction, not the work that should be in an encyclopedia. The article fails to point out the molecular machines already exist in the form of protein/RNA molecules capable of enzymatic activity. This article also fails to show how a synthesized device would be superior to the ones that already exist within biology. The idea that something synthetic and small 'nano-sized' machine imparts magical properties and enhanced capabilities does not follow the scientific literature. Rather, a reduction in size typically results in limited capabilities. Additionally the claim that molecular nanotechnology 'machines' will have capabilities beyond those of a virus is somewhat absurd given the extreme amount of selective evolution that has designed viruses with multiple overlapping'' reading frames within a small set of DNA. See Adeno-associated virus which synthesizes 7+ unique proteins from a 4.7 kb genome.
Perhaps most tragically the article is also written as if the statements within are already accepted fact rather than fantasies of the imagination.
There is a nanomedicine section in the molecular nanotechnology article. Perhaps this article should be merged into that one?>?
- I disagree, nanomedicine does not require medical nanorobots. The ESF definition of nanomedicine is "ensuring the comprehensive monitoring, control, construction, repair, defence and improvement of all human biological systems, working from the molecular level using engineered devices and nanostructures, ultimately to achieve medical benefit."

- I know this is an old section but it looks like nobodies been here for some time. Anyway I have done some work on 'nanorobots' - way back around 1990, the name I generally used was 'assemblers'. The author above is right that assemblers are basically science fiction, they were '10 years' in the future in 1990 and they are still at least '10 years' in the future today in 2012. The problem with assemblers is that it would cost billions -and a vast amount of intensive research- to develop them- and even then they would be almost useless without a lot more work. Possibly I would expect to see them naturally in the evolution of technology in around 60 to 100 years, but I can see them never performing much more than a niche role. The thing that the common SF model really has wrong is that assemblers will be very slow to do almost everything, especially reproduction. And assemblers will probably also require complex difficult environments - like super clean feed-stocks, high vacuum, cryogenic environments, suitable power supply vectors, sufficient cooling capability, and so on. - Solving these problems and creating assemblers that can function say in the human body will probably be at least as difficult as creating the first assemblers themselves.
- As for medicine, if the other problems can be solved it is one of the few areas where these machines could excel. Obviously all living cells are living machines but assemblers would be quite different. For instance one simple application would be hunting down tumour cells and destroying them one by one. Perhaps the most ambitious ideas are- using assemblers to rewrite and repair the neural system directly, or as a partial or complete replacement for the natural immune system, or to completely halt the ageing process. If we had working assemblers that could function in the body most of these would not be impossible or even very difficult.
- An actual (theoretical) application I worked on was a nano-computer that could theoretically replicate an entire human brains neural function directly. The design sketch that I came up with would have had a volume roughly 10,000 times smaller that an average human brain 100 mm^2. Power was the exact opposite, -the calculations for power consumption and heat output were extremely rough but came to about 10 - 40Kw. - In the human brain another rough calculation puts average power consumption and heat output at about 120w, the difference between the two mostly comes from the energy required to keep the simulations elements connected together in real time. The design had 1 million CPU's linked together in an extremely complex network and most of the actual work was in transmitting data from one node to another.
Is there any research currently being conducted in this area? Maybe mentioning some of it, if it exists, would be good for this page.
- I've added a bit on that, and linked to a Nature Materials article for those lucky enough to be able to read it as the citation. I've also added a link to a European Science Foundation report. Average Earthman 13:31, 7 April 2006 (UTC)
Any nanomedicine experts out there?
The article Transfersome concerns an example of medical nanotechnology. It is currently up for deletion, and a rewrite for readability by any editors interested in medical research or nantechnology would help. Plus comments at the deletion debate would be good as well.

Reads like an advertisement?
Is it me or does the Cell repair machines section read like a pamphlet?
- The nanorobots part suffers from the same problem as cell repair machines - it is pure speculation. Most "facts" are at some distant point (undefined) in the future. Almost all of the nanorobotic stuff is "could" or "may". If you are looking for verified facts, they are a minor proportion of these sections, as the objects described do not exist, although extensive "calculations" and computer-rendered images are not in short supply. The only reason this could be in an encyclopedia is because it is so widespread that it has become part of a scientific myth/fiction. But being as Star Trek and particular episodes such as The Trouble With Tribbles have their own wikipedia pages, then I guess we cannot complain about nanobots being in here either.Judge Nutmeg 03:30, 26 May 2007 (UTC)
I was under the impression that the University of Michigan has been experimenting with nanorobots for the past two years. —Preceding unsigned comment added by 22.214.171.124 (talk) 22:11, 22 May 2008 (UTC)
