Nanotechnology - Wikipedia, the free encyclopedia - 1 views

    nanotechnology is an interesting concept. many world governments have invested billions in research for nanotechnology. "Nanotechnology (sometimes shortened to "nanotech") is the manipulation of matter on an atomic, molecular, and supramolecular scale. The earliest, widespread description of nanotechnology[1][2] referred to the particular technological goal of precisely manipulating atoms and molecules for fabrication of macroscale products, also now referred to as molecular nanotechnology. A more generalized description of nanotechnology was subsequently established by the National Nanotechnology Initiative, which defines nanotechnology as the manipulation of matter with at least one dimension sized from 1 to 100 nanometers. This definition reflects the fact that quantum mechanical effects are important at this quantum-realm scale, and so the definition shifted from a particular technological goal to a research category inclusive of all types of research and technologies that deal with the special properties of matter that occur below the given size threshold. It is therefore common to see the plural form "nanotechnologies" as well as "nanoscale technologies" to refer to the broad range of research and applications whose common trait is size. Because of the variety of potential applications (including industrial and military), governments have invested billions of dollars in nanotechnology research. Through its National Nanotechnology Initiative, the USA has invested 3.7 billion dollars. The European Union has invested 1.2 billion and Japan 750 million dollars."

    "Nanotechnology (sometimes shortened to "nanotech") is the manipulation of matter on an atomic, molecular, and supramolecular scale" Nanotechnology is really a manipulation-nanotechnology doesn't happen naturally.

    Pretty good facts on this, I just do not know how reliable this page is, given that it is off of wikipedia. It is interesting to find out just how much countries have invested in nanotechnology. Just may want to check credibility to this page.

    This page has a bunch of great facts on what will be to come of the military and nanotechnology in the future. There are many different topics, and a few references to books and different people's views based on what we are experimenting on now. There is a good amount of embedded hyperlinks in the article.

What It Is and How It Works - 0 views

    I think that this is a great site for learning more about nanotechnology and what it does. It is a government website, so all of the facts are going to be true. There are facts on this site from how big a nanometer is to what nanotechnology can be put to use for. Just from reading the website over once I have already learned so much more about nanotechnology. I think this is a source that will be very helpful in the future.

Nanotechnology In Medicine: Huge Potential, But What Are The Risks? - Medical News Today - 0 views

  •  
    This is another page about how nanotechnology can change medicine forever. There is a section about how we can treat a tumor and be done with it in a short period of time because of little medications. This page also gives great new, interesting facts.

What is Nanotechnology? - 0 views

  •  
    the term nanotechnology was coined back in the 80s by K. Eric Drexler. I'm sure at the time it wasn't much more than a science fiction dream, but now it is a very real technology. "When K. Eric Drexler (right) popularized the word 'nanotechnology' in the 1980's, he was talking about building machines on the scale of molecules, a few nanometers wide-motors, robot arms, and even whole computers, far smaller than a cell. Drexler spent the next ten years describing and analyzing these incredible devices, and responding to accusations of science fiction. Meanwhile, mundane technology was developing the ability to build simple structures on a molecular scale. As nanotechnology became an accepted concept, the meaning of the word shifted to encompass the simpler kinds of nanometer-scale technology. The U.S. National Nanotechnology Initiative was created to fund this kind of nanotech: their definition includes anything smaller than 100 nanometers with novel properties."

    "A basic definition: Nanotechnology is the engineering of functional systems at the molecular scale. This covers both current work and concepts that are more advanced. In its original sense, 'nanotechnology' refers to the projected ability to construct items from the bottom up, using techniques and tools being developed today to make complete, high performance products." This is the definition of what nanotechnology is-building something from almost nothing.

HowStuffWorks "Nanotechnology Cancer Treatments" - 2 views

    "But nanotechnologists think they have an answer for treatment as well, and it comes in the form of targeted drug therapies. If scientists can load their cancer-detecting gold nanoparticles with anticancer drugs, they could attack the cancer exactly where it lives. Such a treatment means fewer side effects and less medication used. Nanoparticles also carry the potential for targeted and time-release drugs. A potent dose of drugs could be delivered to a specific area but engineered to release over a planned period to ensure maximum effectiveness and the patient's safety." Nanotechnology can be a better, more efficient way of getting rid of cancer cells.

    This seems like a great website to use. It backs up all of its statements with facts, so we know we can rely on it. I know this source will come in handy later because it actually explains how nanotechnology is used in some medical fields. I also know this is reliable because they list the sources that they used. This seems like a very official site to use.

Nanotechnology Introduction - 0 views

  •  
    "The term "nanotechnology" has evolved over the years via terminology drift to mean "anything smaller than microtechnology," such as nano powders, and other things that are nanoscale in size, but not referring to mechanisms that have been purposefully built from nanoscale components. See our "Current Uses" page for examples. This evolved version of the term is more properly labeled "nanoscale bulk technology," while the original meaning is now more properly labeled "molecular nanotechnology" (MNT), or "nanoscale engineering," or "molecular mechanics," or "molecular machine systems," or "molecular manufacturing." Recently, the Foresight Institute has suggested an alternate term to represent the original meaning of nanotechnology"
