To what extent should humans fear further advancement in Nanotechnology?
Although nanotechnology isn’t something you hear about every day, it is often useful to know a bit about it considering one day it could completely take over our lives and change the world as we know it. Nanotechnology refers to a field of research and innovation linked with ‘building things’ on a molecular and atomic scale. A nanometre is equivalent to one billionth of a meter and when we are dealing with such scales, the rules of physics and chemistry no longer apply. In turn, this will allow us to undergo “atomically precise engineering” which could have a positive impact on every one of us. Picture what we could do when we have carbon nanotubes (rolled up sheets or graphite that are 1000 times thinner than air) that are 100 times stronger than steel yet six times lighter. Nanotechnology may seem very futuristic, however it is not something that is new to us. We have already built many machines/materials that use nanoparticles (particles with a range of 1nm to 100nm), some of which include self-cleaning glass, swimming pool disinfectants, scratch resistant coatings and safer yet more effective lithium ion batteries. Now we are looking into using these nanoparticles for more serious issues, for example in curing cancer and developing more effective nuclear weapons. But is this something that we should worry about?
Much of nanoscience and many nanotechnologies are concerned with producing new or enhanced materials. The reason most nanotechnology researchers are so excited is mainly because they can reinforce materials to make them not only stronger, but also lighter. The products that we can get from this will have new electronic, optical and mechanical properties. One…...

...S. National Nanotechnology Initiative was created to fund this kind of nanotech: their definition includes anything smaller than 100 nanometers with novel properties.Much of the work being done today that carries the name 'nanotechnology' is not nanotechnology in the original meaning of the word. Nanotechnology, in its traditional sense, means building things from the bottom up, with atomic precision. This theoretical capability was envisioned as early as 1959 by the renowned physicist Richard Feynman.I want to build a billion tiny factories, models of each other, which are manufacturing simultaneously. . . The principles of physics, as far as I can see, do not speak against the possibility of maneuvering things atom by atom. It is not an attempt to violate any laws; it is something, in principle, that can be done; but in practice, it has not been done because we are too big. — Richard Feynman, Nobel Prize winner in physicsBased on Feynman's vision of miniature factories using nanomachines to build complex products, advanced nanotechnology (sometimes referred to as molecular manufacturing) will make use of positionally-controlled mechanochemistry guided by molecular machine systems. Formulating a roadmap for development of this kind of nanotechnology is now an objective of a broadly based technology roadmap project led by Battelle (the manager of several U.S. National Laboratories) and the Foresight Nanotech Institute.Shortly after this envisioned molecular machinery is......

Prospects of Market Volumes and Shares Economics Essay

...nanotechnology market. The model includes a first phase up to 2004 with some nanotechnology incorporated in high-tech products. The next phase up to 2009 will bring breakthroughs for nanotechnology innovations. Nanoelectronics would dominate this market. In a third phase from 2010 onwards, nanotechnology will become commonplace in manufactured goods with healthcare and life science applications entering the pharmaceutical and medical devices markets. Nanobiotechnologies will contribute significantly to the developments in the pharmaceutical industry. Basic nanomaterials as such will lose importance at this time. Lux Research (2004) estimates a market share for nanotechnology products of 4 % of general manufactured products in 2014, with 100 % nanotech in PCs, 85% in consumer electronics, 23 % in pharmaceuticals and 21 % in automobiles. This would lead for nanotechnology to an overall share of 15 % of the global manufacturing output in 2014. In an analysis of the drug delivery market, estimates for nano-enabled drug delivery market support the above presented projections. The expected development of the market for nano-enabled drug delivery shows an average annual increase of 50 % between 2005 and 2012. The increase of the market share follows a same path, but with slightly lower rates. In 2012, about $4.8 bn will be earned with nanotechnology on the drug delivery market, which would be a market share of 5.2 %. If the development continues, this market share will increase to......

Nanotech Super Nutrients

... Then, instead of a gelatin capsule you have a very delicate capsule made of a fat globule. This little fat capsule disguises the contents so well that it goes right into the bloodstream, totally bypassing all of the digestive complications present with traditional delivery mechanisms. Many supplements get stuck somewhere in the digestive process and never enter your bloodstream at all. Many get stuck in the liver. Some don’t even make it past your stomach. Liposomes slip right on through each phase. As I write this report, 11 pharmaceutical drugs use liposomal encapsulation as a delivery mechanism and several more are under the approval process. These drugs range from oral vaccines to antifungals to analgesics. So, liposomes as a nanotech delivery mechanism for drugs is recognized by the traditional medical community. Using them as a delivery mechanism for nutrients, however, is not. This is probably due to the aforementioned (and most of the time justifiably) conservative nature of traditional medicine. The slow speed and high cost of the approval process is probably making such recognition impractical. But this hasn’t stopped biohackers from experimenting with liposomal encapsulation to deliver vitamin supplements. From my examination of the science, I believe this is a really positive trend. Since liposomes are usually composed of lecithin and whatever it is you are encapsulating, they appear to be safe. But this opinion does require two caveats … First, it......

Nanotech in Manufacturing

...Introduction: Body: Description of the technology and explanation of the associated science (Chris) So what is nanotechnology? Webster dictionary defines nanotechnology as the science of manipulating materials on an atomic or molecular level. Basically nanotechnology is the study and application of matter on the atomic level between 1 and 100 nanometers (nm). A nanometer is one-billionth of a meter. To get an understanding of how small this is, an atom has a diameter of about 0.1nm and the nucleus of an atom is much smaller, about 0.00001nm. Nanotechnology is the science that is used to rearrange molecules on the atomic level so that each atom is essentially put in the most efficient place. This is best clarified by Dr. Ralph Merkle, Ph. D., of the Georgia Institute of Technology in this way: “Manufactured products are made from atoms, and the properties of those products depend on how those atoms are arranged. If we rearrange the atoms in coal, we can make diamond. If we rearrange the atoms in sand and add a few other trace elements, we can make computer chips. If we rearrange the atoms in dirt, water, and air, we can make potatoes” (Ghadar & Spindler). Biologist, chemists, physicists and engineers are involved in studying substances at the nano-scale, thus making nanotechnology an interdisciplinary field of science (Bonsor & Strikland). Scientists are creating new materials by manipulating molecules at the atomic level. Nanosize super particles......

Normative Decision Process of an Investment Gift for a Nanotechnology Center

...is the Nanotechnology Center at the SUNY IT campus to provide for both academic experience and commercial research and development studies. According to Nano.gov, nanotechnology is “science, engineering, and technology conducted at the nanoscale, which is about 1 to 100 nanometers.” Why is nanotechnology important? The use of nanotechnology and nanoscience can be utilized in all other broad science fields including chemistry, biology, physics, materials science and engineer. The university, in partnership with SUNY College of Nanoscale Science & Engineering (CNSE), will deliver a Nanotechnology Center that can facilitate innovation in a critical and evolving field. The creation of the Nanotechnology Center will also include leading nanotech companies such as Advanced Nanotechnology Solutions Incorporated, SEMATECH, Atotech, and various partners (SUNY IT, 2014). The university has many options on investing the $20 million including updated facilities for students, facilities for collegiate sports programs, or other technology programs. The first option of new facilities for students would benefit the students that utilize the campus for day-to-day lectures, work and resources. Facilities such as new dorms, classrooms and laboratories would compliment the SUNY IT recent expansion in 2011-2012. The reality is that SUNY IT had just expanded campus infrastructure by investing $13 million on a student center, $20 million on a field house and $23.5 million on a residence hall...

Nano Technology

...Nanotechnology ("nanotech") is 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. Until 2012, 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 size is......

Nanotechnology in the Food Industry

...buy the mature product. The unwillingness of food companies to talk about their current use of nanotechnology in food production and their plans for its future use is a huge a blow to transparency. Without any requirement for manufacturers to label nano-foods, or any willingness on the part of companies to do so voluntarily, there is no way for people to choose whether or not to eat nano-foods. This breach of public trust is compounded by government's failure to regulate nano-food products to ensure that workers, the public and the environment do not face unsafe exposure to nanomaterials. Current hurdles & perceived dangers The recession has probably put a break on nano research. Because commercialization is often some way off nanotech research projects can come under threat when budgets are squeezed. Not enough is presently known about the effects of NMs (nanomaterials) on the human body. Matter has different behavior at nano-scales than at normal scale. Aluminum, for example, is stable in the ‘big world’ but explosive at nano-levels. Some metals will kill bacteria at nano-scale – hence the interest in using them in food packaging – but what will happen if they get off the packaging and into us? No one seems to know. The size question is central to these concerns. Nano particles that are under 100 nano-meters wide – less than the size of a virus – have unique abilities. They can cross the body’s natural barriers, entering into cells or through the liver into the......

Nanotech Case Study

...Market Analysis The nanotubes market is young and unsaturated. There are currently three major players that are present; Carnot, Nan Teck, and Nanoburger. There are other minor players that are beginning to take hold in the market coming out of the Asia region, however, till now these companies pose no major threat in gaining significant market share in the raw nanotubes business. There are three main products produced by the nanotube producers, these three products are; raw nanotubes, technical liquids that use nanotube dispersions, and fibers containing nanotubes. The raw nanotube is currently the most demanded product. Demand far out-weighs supply in this sector, and none of the competitors currently has the capacity to produce more than one kilo of raw nanotubes per month. It seems that the future of the market will rest on the technology that can be developed from nanotube fibers, however this technology is a minimum of 5 years away from being commercially viable. Success in the nanotubes market relies on building a reputation for producing high quality nanotubes and the ability to build capacity in the near future to meet demand. RPP Analysis In relative performance to the other companies, Carnot produces a nanotube that is of a very high quality, Nan Teck also produces a high quality product and Nanoburger produces a low quality product, however they have the best reputation among the group, which allows them to be the market leader. However, Carnot and......

...NANOTECHNOLOGY Nanotechnology is the study of manipulating matter on an atomic and molecular scale. Nanotechnology is the science of very small things, usually smaller than one hundred nanometers which is smaller than a strand of the human hair even. It is an expected future manufacturing technology that will make most products lighter, faster, stronger, cleaner, and most of all less expensive but more precise. The world of nanotechnology is so broad, and touches on almost every topic of science. Nanotech is one of our biggest pushes into the future of our everyday living. There are hundreds of billions of research being conducted all around the world every day; in fact products seem to be changing as much as a daily routine nowadays. The research seems to be limitless on what we are able to do using nanotech, for instance when looking at the most common things we use such as: automobiles, computers, cell phones, televisions they seem to change instantly. Nanotechnology has the potential to change every part of our lives. Nanotechnology affects all materials: ceramics, metals, polymers, and biomaterials. New materials are the foundation of major technological advances. In the coming decade nanotechnology will have an enormous impact. Future advances could change our approaches to manufacturing, electronics, IT and communications technology making previous technology redundant and leading to applications which could not have been developed or even thought about, without...

...devices. Energy consumption will be reduced due to newly developed lubricants with inorganic buckyballs, soccer ball shaped carbon molecules that reduce friction. Storing hydrogen for fuel cell cars will be easier with the graphene layers that increase the binding energy of hydrogen to the graphene surface. This could result in a higher amount of storage and a lighter fuel tank. Another major field that uses nanotechnology and will benefit from it greatly is in the field of medicine. Professor Johannes Heitz from the University of Linz, Austria said, “About 10 years ago, scientists discovered the important influence that nano-structures had on the way a line of cells would develop. It was the beginning of an entire new scientific field (Nanotech Medicine to Rebuild Damaged Parts of Human Body, 2011).” One way nanotechnology has impacted medicine is the ability to help grow cells back in or on person’s body. One way this is shown is the ability to help grown skin cells back on a burn victim. Usually the material used now will cause imperfection and make it inefficient. With nanotechnology it will be possible to grow the cells back with little to no imperfections. Many more applications that involve nanotechnology are used in medicine that could possibly cure cancer or even replace whole organs. Nanotechnology will also benefit the spaces programs. Currently there is ongoing research on carbon nanotubes. These nanotubes will make spaceships lighter and more stable......
