Nanotechnology, A Revolutionary Undertaking

Nano technology, a revolutionary scientific undertaking, involves entry and utilization of materials, devices, or systems on an extremely small scale, usually on an tingeic or molecular scale, and is originally undergoing detonative development on some(prenominal) fronts. (see photo 1) These fronts include the creation of materials, medicine, electronics, and efficacy production. With nanotechnology, diminutive devices go off be created with single molecules or atoms. The reason this is so effectual is that anything provoke be created and do on a scale so tiny. It shadower be used to extend to and treat diseases, advance cogency efficiency, create smaller and to a commodiouser extent powerful computers, and perchance change surface coarseer things in the future. iodine part of breeding that has and ordain greatly amass from the advances of nanotechnology is medicine. Nanotechnology go break allow doctors to more(prenominal)(prenominal) than effectiv ely nominate diseases and deliver drugs. It whitethorn even allow doctors to engineer consistency tissue atom by atom, which would be very useful in the field of infection, amputation, or the extremity for youthful organs. Nanotechnology flip greatly improve the diagnosis of diseases by how versatile nanotechnology deal be. Small, nanosizingd robots or particles can be sent into the personify with a computer reinforced in. Whenever the nanobots reach certain prison cells that read some sort of disease, the cell properties can be relayed foul to the doctors (see photo 2). Researchers at Harvard University deal already synthe coat a aerated nanowire that can detect the straw man of cancer. The reason this is gilt-edged to current diagnosis methods is because of its improved reliability. The nanobots physically go into the body and locate diseased cells, which is untold more reliable than personal credit line tests, urine samples or even magnetic resonance tomograp hy scans, all of which can miss important in! dicators for a disease. The nanodevices can cypher cells and sample it?s properties, by chance even interact with the cell, and send data back to the doctors. Drug rake ordain withal greatly improve, perhaps even more so than the diagnosis of drugs. One of the main reasons nanotechnology can so benefit drug delivery is that nanotechnology has the voltage to actively fair game aras that need treatment (see photo 3). With traditional drugs, when it is delivered into the body, it must dust passim the whole body, which consequently can cause expression effects. With nanotechnology, this puzzle is eliminated, as they can be directed to a ad hoc part of the body. The surroundings is another aspect of life that pass on be greatly collisioned by the advance of nanotechnology. oerflowing solar energy hits the earth in a secondment to sufficiently power the earth?s universe of discourse for a week. Extensive research is currently being done on how nanotechnology can con vert solar energy into total heat in give the sack cells. Scientists nurse developed a process that utilizes nanotechnology, which shows great promise in this field. Currently however, the energy production of fuel cells is very inefficient. In fact it is so inefficient that the personify of electricity produced by solar cells is quaternary times greater than electricity produced by nuclear or fossil fuels. genus Arizona State University scientists deal proposed to build arrays of transmitting aerial made of metal particles at a nanoscale level, which could concentrate clean-living and make the changeover process from solar energy into electricity much more efficient and much less costly than that achieved by te solar cells. These arrays of antennas could be theoretically set on a thin film and laid crossways the roof of a house. Nanotechnology ordain also greatly impact the ICT industry, especially in the aspects of size, energy efficiency and effectiveness in ter ms of work out power. Engineers have proposed to mak! e a computer completely sedate of nanotechnological elements. What we are proposing is a new type of computing computer architecture that is only found on nano mechanical elements, said prof Robert Blick of the University of Wisconsin-Madison. The smaller transistors are, the more you can fit on a cow dung. Consequently, the power of the microchip increases. (See photo 4) Another major benefit of nanochips is the fact that they are not affected by EMP?s. EMP stands for electromagnetic pulse, and these can be used by enemies to knock out all electronics inwardly a certain range. This is why the creation of nano-sized transistors is such a significant advancement of nanotechnology. Aside from current nanotechnological developments and applications, there are many speculations as to how nanotechnology leave alone arise in the future. One greatly discussed practical advancement is in surgery. With nanotechnology, surgeries could be performed without even having to cut the patie nt open. Since nanobots are so small, it is possible that they could carry and distribute single atoms one by one. This delegacy limb reconstruction, organ reconstruction, disassembly of tumors and cancer, the repair of catching defects and possibly even the halt of the aging process break polish possibilities. There are also several ways the milieu exit be affected by nanotechnology in the future. Batteries volition be summate smaller and more powerful. Molecule sized solar cells can be mixed into road asphalt to perk solar energy in substantial amounts. We may also build nanobots that eat pollutants and contaminants, which could clean up anele spills and perhaps the o-zone layer.13 In the ICT industry, microchips go out continue to shrink in size and become faster and more powerful. Hard drives centimeters commodious ordain be able to hold enormous amounts of data, and in the end microchips will be able to be embedded in our clothes and even in our body.13 In the military, soldiers can pall a specialized suit that! utilizes nanotechnology. It will be flexible, and will be able to harden upon high power impacts. clothing will be able to store high amounts of energy that will allow for proved speed, strength, and possibly even invisibility. Although nanotechnology will greatly benefit many aspects of our life, there are thus far limitations to how much they can benefit us. In medicine, one of the great concerns of nanotechnology is that they are so small. Elements always behave differently when scale down to nano sizes. Aluminum, a relatively harmless element becomes explosive when shrunk to nano sizes.

Doctors busy that nanovehicles may be able to cross the blood-brain barrier, a tissue layer that keeps dangerous chemicals in the blood drift away from the brain. Nanotechnology isn?t always good for the environment. Silver nanoparticles that are in over 200 anti-microbial products can mutate and shovel in embryos of fish when they enter their ecosystems. Often, residues from these products are washed down the debilitate and into the ocean, contaminating ecosystems. Nanotechnology is the technology of the future, and the possibilities that come with it are endless. Nanotechnology may have disadvantages, however the order of magnitude of the benefits that come out of it greatly outweigh the limitations. Nanotechnology will have fantastic benefits for all of mankind, and lastly could become the standard in all areas of technology. It will be beneficial to medicine and the environment, and enhance military protection and the ICT industry. Nanotechnologies potential for mankind is colossal, and should all of thes e things come true, the world will never be the same.!
