...Nanotechnology Nanotechnology has been an anticipated technology due to it giving complete and inexpensive control of the structure of matter. The thought of this technology came from the mind of Richard Feynman, a physicist, in 1959. The way Feynman first described nanotechnology was, “a process by which the ability to manipulate individual atoms and molecules might be developed, using one set of precise tools to build and operate another proportionally smaller set (History and Future of Nanotechnology, 2009).” Manufacturing at the molecular scale will enable the construction of cell repair machines, computers smaller than a cubic micron, and even personal manufacturing. Molecular manufacturing or nanomanufacturing is where it all starts. Nanomanufacturing is the manufacturing of nano-scale materials, structures, devices, and systems. There are two approaches to nanomanufacturing, the top-down approach or the bottom-up approach. The top-down approach reduces large pieces of material down to the nanoscale. This approach uses more material and can lead to waste if excess material isn’t used. The second approach, the bottom-up approach, creates products by starting at the atomic or molecular level and building the products from the ground up. This process is very time consuming. With these two approaches there are new processes that enable nanomanufacturing which are (Manufacturing at the Nanoscale): 1. Chemical vapor deposition – a process where chemicals react to produce...

...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.[3] Nanotechnology as defined by...

...Nanotechnology Patricio Peña Medina June 14, 2013 Composition II Professor M. Putman Research Paper It’s the biggest technology challenge since the information super high way. Engaging scientist, entrepreneurs and governments form countries all over the world. Public debates, press conferences and expos around the world this technology is revolutionizing science. Not visible to the naked eye, tiny self-assembling Nano systems offer big solutions to some of the world’s most complex problems. This is science on the Nano scale, or scientist it’s the largest topic with hundreds of thousand possibilities. To put things in more of an understandable perspective, the smallest things that the human eye can make out is around 10,000nm. To aid in further understanding of these measurements more than 100 students from Rice University by designing an immense single-walled carbon nanotube. The nanotube measured 1180 feet long (Williams & Adams 23). So what is nanotechnology? 1 nanometer is 1 billionth of a meter, about the size of six carbon atoms or less than one water molecule almost too small to imagine (Williams & Adams). Nano technology is the science of interacting with atoms and molecules to modify the way they behave; for example by chemical creating Ferro fluids or liquid magnets the exhibit strange behavior due to external magnetic fields. Or by fabricating Nano scale semiconductor crystals known as quantum dots which are sometimes called artificial atoms...

...NANOTECHNOLOGY Nanotechnology, or Nanotech for short, is the study of the control of matter on a molecular or atomic scale. There is a range in size of nanoparticles, from 100nm to 1nm. Scientists have been trying to investigate whether we can control matter on the atomic scale. It has been debated that nanotechnology could widen the horizons on the medicine, applications and electronics front. A nanometre is one billionth of a metre. This just shows the size of the technology scientists are working with. Nanoparticles are versatile and have different properties to the substance of a larger size. Nanoparticles are already being used in the consumer market, but there has been debate over safety risks. Nanoparticles are too small to be seen through a microscope, which is astonishing to imagine a particle that cannot be observed through a microscope. Special Properties Of Nanoparticles * Nanoparticles have different properties to normal sized pieces of the substance. For instance, pieces of gold are gold-coloured, whereas gold nanoparticles are a dark-red or even black colour. These different properties can be very useful to scientists and producers. Nanoparticles in pharmaceuticals: Some cosmetics contain liposomes, which are fatty nanoparticles. These have great potential in the pharmaceutical industry, because they directly apply medicines to the skin Sun-blocks contain Titanium dioxide nanoparticles. These are good because they block harmful UV rays from the...

...Nanotechnology: Everything from Nothing In chapter 4, Kaku introduces readers to nanotechnology, the manipulation of matter on an atomic scale. Using nanotechnology would enable the government and companies to manipulate individual atoms, which could spur a second industrials revolution. Molecular manufacturing creates new materials that we can only dream about today. These materials will be super strong, super light, and they will possess amazing electrical and magnetic properties. Kaku continues the chapter by explaining that in the near future, we can expect a new variety of nanodevices that may revolutionize modern medicine. He begins with the idea that scientists will obtain the ability to utilize nanomachines in human bodies. Kaku explains that part of this technology is already available today in the form of a smart pill, which is a tiny instrument the size of a pill that a human swallows. Scientists track the smart pill electronically and they instruct it to deliver medicines to the proper location. The nanoparticle is a much smaller device and Kaku describes it as a molecule that can deliver cancer-fighting drugs to a specific target. One-step beyond the nanoparticle is a nanocar, which is a device that scientists can guide through the human body. The device would detect and kill of cancer cells. Kaku also introduces the idea that DNA chips in the form of tiny sensors in our clothing, bodies, and bathrooms will constantly monitor our health and detect diseases...

...Nanotechnology Applications Daniel Shelton Contemporary Applications of the Sciences | SCI215 A03 Argosy University “Nanotechnology is an idea that most people simply didn’t believe” (Merkle). They’re many applications in the field of nanotechnology. Taking a further look into this particular branch of material science we can see that on the atomic scale this matter can be manipulated. This branch deals with engineering in general but the three I chose to discuss are the fields of: medicine, agriculture, and space exploration. In these three fields we will expand them and discuss on how these current and future applications are applied and examples of them in detail. These fields are used every day through the process of nanotechnology at its very basis. Nanotechnology however; has the very power to impact every aspect of society whether we realize it or not. Currently in the realm of medicine through applying this concept with nanotechnology its being used already for the very foundation of delivery systems for drugs that are new and vastly effective. In the development at its early stages, research of regeneration of nerves as scaffolding is being used. The National Cancer Institute has begun a very alliance with the Nanotechnology in Cancer has invested a lot of hope in this nanomedicine branch. The breakthroughs through this process could help in terms of treating, diagnosing, and helping to predict multiple types or forms of cancer. In the upcoming years through...

...Kassondra Deneen Hughes Nanotechnology Argosy University Professor Merwin SCI215 Nanotechnology Television is a form of entertainment, which has changed the way people think about science. Science was once viewed by many as boring or too complicated but thanks to shows like The Big Bang Theory that has changed. The show and its quirky actors teach us something different each show. One thing that I learned is that physics is the study of nature and properties of matter and energy. When the show first came on there was a chalk board in their living room that had a lot of numbers on it and Sheldon was attempting to figure out some mind boggling equation that involved a lot of small numbers that looked like big numbers. I have even heard one or all of those scientist talks about the nanotechnology. Most people did not know exactly what they were talking about and that’s why a lot of people did not like the show. It was hard to follow if the person did not know anything about nanotechnology. But because of the comedy the shows conversation about certain aspects of the scientific process is a little easier to understand. Unfortunately, nanotechnology is such a broad field it has to be broken down into smaller increments, how nanotechnology affects medicine is a great place to start. Nanotechnology has become a very popular science because it helps a person to understand it takes a lot of atoms to make up anything on the earth. It makes it much easier to understand...

...------------------------------------------------- Nanotechnology THE FUTURE AND PRESENT Ap So what exactly is nanotechnology? With that question there is a lot of answers. The definition of nanotechnology is, “the branch of engineering that deals with things smaller than 100 nanometers (especially with the manipulation of individual molecules)”Nanotechnology will allow the construction of smaller circuits and computers. Smaller circuits will run faster enabling much faster computer speeds, and will give them much greater lives as well. That means a laptops efficiency could be increased by millions, living longer and working faster which would be more value for the money that you pay. I found an article on the internet from Royal society of chemistry that talks how nanotechnology will actually have a good impact on the environment in the future. It says “For the environment and energy, nanotechnology will have a significant impact. For instance, nanometer sized solar cells could be developed to provide much of the energy needed around the world and nanomaterial’s will increase the efficiency of fuel cells and batteries. I the future nanotechnology will be used to tackle environmental problems, new “green” processing technologies will minimize the generation of undesirable by-product effluent by curbing emissions.” Nanotechnology is a relatively new and emerging field of science, it was first alluded in 1959, but it remained largely theoretical until the 1980s...

...Nanotechnology Applications Kareema L. Smith Argosy University Nanotechnology can be described as manufacturing and or engineering on a small scale, this can be related to numerous areas of study and development – nanotechnology is utilized by several fields such as medicine, engineering, information technology, wild life, agriculture and the list goes on. When thinking of nanotechnology there is no way to tell what the future holds for scientist who research and study this field and how it will affect humans daily, but I will go on and describe some of the applications we and our society has benefited from the study of nanotechnology. In the medical field nanotechnology has be utilized as a tool to offer early detection of an oncoming disease or virus. Nanoparticles are deposited into the body, these particles has small fluorescent blotches that were engineered to mark antibodies. By doing so these fluorescent marks can find or identify disease even at the very onset of contracting the virus. Nanotechnology is also offering faster diagnoses of diseases, in some cases results of diagnoses can take weeks to come back in causing the patient to stress and worry. Utilizing this technology doctors are now able to use a nano-device known as ‘lab-on-chip’, by only using a small sample and this small chip. The samples can be analyzed quickly, so quick that some diagnoses can be read almost instantly. The study and application of nanotechnology is also benefitting the food...

...Nanotechnology Nanotechnology, which is widespread subject, is what is likely to be the driving force of many scientific changes of our earths future. It’s the technology of manipulating matter at the nano scale. Nanotechnology is applied in countless different fields such as science, health care, agriculture, security, computing etc. The ground breaking developments that are made in these various fields due to nanotech is why the world will continue to invest its time and money into the subject matter. “Many experts even predict that Nanotechnology is going to have as significant a place in the field of science and technology as the steam engine had at the time of its invention. Due to the potential it bears most developed and developing countries are making significant investment into nanotechnology research and development where the combined investment from the private and public sector is estimated to be around $12 billion annually.” (Michelson et al, 2008) The revolution of nanotechnology is not only expected to make many products and services friendlier economically, but is also going to allow for the miniaturization of control systems. Diseases will be more simple to cure, and we will have new cures for diseases that we do not yet have cures for. On the contrary with advantages come disadvantages. There are many widespread discussions regarding the negative effects of nanotechnology. Nanotechnology has its benefits but can also be lethal if used improperly...
