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 gave a good amount on how nanotechnology can change the future of medicine, from taking pills to cancer. It also talks about nerve regeneration and how that is in the near future with nanotechnology.

"Nanotechnology is already being used in products in its passive form, such as cosmetics and sunscreens,"

"Nanotechnology medical developments over the coming years will have a wide variety of uses and could potentially save a great number of lives. Nanotechnology is already moving from being used in passive structures to active structures, through more targeted drug therapies or "smart drugs." These new drug therapies have already been shown to cause fewer side effects and be more effective than traditional therapies. In the future, nanotechnology will also aid in the formation of molecular systems that may be strikingly similar to living systems. These molecular structures could be the basis for the regeneration or replacement of body parts that are currently lost to infection, accident, or disease. These predictions for the future have great significance not only in encouraging nanotechnology research and development but also in determining a means of oversight. The number of products approaching the FDA approval and review process is likely to grow as time moves forward and as new nanotechnology medical applications are developed."

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.

A nanometer is one billionth of a meter. this means that when nanomites they will be so small that we wont even e able to see them through a microscope. "In order to understand the unusual world of nanotechnology, we need to get an idea of the units of measure involved. A centimeter is one-hundredth of a meter, a millimeter is one-thousandth of a meter, and a micrometer is one-millionth of a meter, but all of these are still huge compared to the nanoscale. A nanometer (nm) is one-billionth of a meter, smaller than the wavelength of visible light and a hundred-thousandth the width of a human hair"

"In order to understand the unusual world of nanotechnology, we need to get an idea of the units of measure involved. A centimeter is one-hundredth of a meter, a millimeter is one-thousandth of a meter, and a micrometer is one-millionth of a meter, but all of these are still huge compared to the nanoscale. A nanometer (nm) is one-billionth of a meter, smaller than the wavelength of visible light and a hundred-thousandth the width of a human hair [source: Berkeley Lab]. As small as a nanometer is, it's still large compared to the atomic scale. An atom has a diameter of about 0.1 nm. An atom's nucleus is much smaller -- about 0.00001 nm. Atoms are the building blocks for all matter in our universe. You and everything around you are made of atoms. Nature has perfected the science of manufacturing matter molecularly. For instance, our bodies are assembled in a specific manner from millions of living cells. Cells are nature's nanomachines. At the atomic scale, elements are at their most basic level. On the nanoscale, we can potentially put these atoms together to make almost anything" Nanotechnology is measured in a nanometer, which is one-billionth of a meter. Nanotechnology is extremely small, and can help create something from something not seen with human eye.

"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"

nanotechnology is a branch off of nanotechnology. they are small machines that can be used for anything. "Nanorobotics is the emerging technology field creating machines or robots whose components are at or close to the scale of a nanometer (10−9 meters).[1][2][3] More specifically, nanorobotics refers to the nanotechnology engineering discipline of designing and building nanorobots, with devices ranging in size from 0.1-10 micrometers and constructed of nanoscale or molecular components.[4][5] The names nanobots, nanoids, nanites, nanomachines or nanomites have also been used to describe these devices currently under research and development"

"Nanotechnology is being applied to cancer in two broad areas: the development of nanovectors, such as nanoparticles, which can be loaded with drugs or imaging agents and then targeted to tumours, and high-throughput nanosensor devices for detecting the biological signatures of cancer. Combined, such technologies could lead to earlier diagnosis and better treatment for patients with cancer." Nanotechnology can also help see cancer in its earlier stages to help stop it from spreading.

Here is another great source that I found. It is another government website that is reliable, and completely full of facts. It gives some new perspectives on how to grasp how small a nanometer and how small the nanoscale really is. It also lists several ways that nanotechnology can be used. This is a site that will increase almost everybody's knowledge on nanotechnology.

Great page! A lot of good, strong facts. I liked the size part about just how big nanotechnology is, compared to a human hair.

"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.

This page talks about the many applications for nanotechnology in the near future and what they can do, from keeping food from spoiling to diagnosing disease.

"Nanotechnology will be at first rare and expensive and, by the end of the century, commonplace and cheap, largely fulfilling the predictions of pioneering scientists"

"Q: You believe that within about two decades, nanotechnology will replace the computer industry as the field of the biggest technological innovations, right?"

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.

This website focuses all on one branch of nanotechnology: nanobots. The website lists the wide variety of jobs nanobots can do, from cleaning entire kitchens while no one is home to being injected in the bloodstream to kill cancer cells before they form a tumor. This website seems to be very official and is entirely dedicated to spreading the knowledge of every part of nanotechnology. I recommend everyone in nanotechnology to look over this website, because it has such a vast array of knowledge on the topic.

Nanotechnology in agriculture is a big deal, especially for us Midwest citizens. This page talks about raising crop production and treating plant-related diseases.

"How has the approach toward nanotechnology changed as we've learned more about nature?"

future of nano tech video. talking about what it can dp

This page seems to be reliable to me because the interviewees were very prestigious professors at multiple universities. Also, one of the interviewees was a futurist who devotes his time to predict the future and what it will be like based off of basic sciences. That is why this video seemed to be legit to me.

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.
