Advantages & Disadvantages of Nanotechnology
Understanding, shaping and combining matter at the atomic and molecular scale is called nanotechnology. Nanotechnology encompasses science, medicine, engineering, computing and robotics at this scale, called the nanoscale. Nanotechnology offers the potential for new and faster kinds of computers, more efficient power sources and life-saving medical treatments. Potential disadvantages include economic disruption and possible threats to security, privacy, health and the environment. Nanotechnology is already making new materials available that could revolutionize many areas of manufacturing.
Nano-technology is among the most advanced fields of science and like every advanced field, it is full of both risks and opportunities. Several government and private bodies are investing in research on nanotechnology since the field holds immense potential. While the technology holds strong potential in various areas from medicine to IT and energy as well as environment, several risks associated with nano technology have also been noted. Despite these risks, nano technology remains a potentially attractive area and any major development in this field could become the next major breakthrough in the field of science and technology. The potential of nanotechnology is igniting debate and discussion all over the world.

THE ADVANTAGES AND DISADVANTAGES OF NANOTECHNOLOGY
While nanotechnology is seen as the way of the future and is a technology that a lot of people think will bring a lot of benefit for all who will be using it, nothing is ever perfect and there will always be pros and cons to everything. The advantages and disadvantages of nanotechnology can be easily enumerated, and here are some of them:. To enumerate the advantages and disadvantages of nanotechnology, let us first run through the good things this technology brings:. When tackling the advantages and disadvantages of nanotechnology, you will also need to point out what can be seen as the negative side of this technology:.
The field of nanotechnology relates to the study and micromanipulation of nanostructure properties at dimensions between 1 and nanometers. Nano-science has a multitude of applications, including technology, manufacturing and medicine. This technology is on the verge of many innovative advances, which excites and concerns many scientists. Researchers in nano-technological fields observe and manipulate anatomic properties of various materials up to 1 nanometer in size. Nanotechnology continues to grow as a field and brings together a multidisciplinary group of researchers, including biologists, chemists, physicists and engineers.
Applications, advantages and disadvantages of Nanotechnology
They are called nanoparticles when they have all three dimensions in the nanoscale. Intrinsic properties of engineered nanomaterials, designed for a specific purpose, provide unique functions to these nano-objects, whose manufacture and use are exponentially increasing. Dentistry benefits of nanotechnology in disease prevention and diagnosis, in bone regeneration, restaurative dentistry, dental implants and tissue regeneration. As in every human domain, evidence begins to point to the fact that along with the positive changes brought by nanotechnologies, they may also cause toxic effects for human health and for the environment security. The mechanisms of nanotoxicity are not yet completely understood, but toxic effects produced by nanoparticles have been recognized for pulmonary, reproductive, cardiac, digestive, cutaneous and immune levels. Nanomaterials can also cause air, water and most important a soil persistent form of pollution, which is too small to be detected easily, making nanopollution another manmade unwanted environmental impact, with uncertain effects in the long term. Larger and multicenter studies are needed to determine the human reactivity and the fate of the nanoparticles in the environment before large-scale nanotechnology is completely settled.
Nanomedicine is the process of diagnosing, treating, and preventing disease and traumatic injury, of relieving pain, and of preserving and improving human health, using molecular tools and molecular knowledge of the human body. Nanomedicine's nanorobots are so tiny that they can easily traverse the human body. Scientists report the exterior of a nanorobot will likely be constructed of carbon atoms in a diamondoid structure because of its inert properties and strength.
Сьюзан понимала, что сегодня любопытство Хейла может привести к большим неприятностям, поэтому быстро приняла решение. - Это диагностика, - сказала она, взяв на вооружение версию коммандера. Хейл остановился: - Диагностика? - В голосе его слышалось недоверие. - Ты тратишь на это субботу, вместо того чтобы развлекаться с профессором.
