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 volatile development on umpteen fronts. (see photo 1) These fronts include the creation of materials, medicine, electronics, and muscularity production. With nanotechnology, diminutive devices go off be created with single molecules or atoms. The reason this is so serviceable is that anything provoke be created and through on a scale so tiny. It set up be used to take for and treat diseases, advance efficiency efficiency, create smaller and to a commodiouser extent powerful computers, and by chance thus far greater things in the future. iodine part of feel that has and ordain greatly hit from the advances of nanotechnology is medicine. Nanotechnology go break allow doctors to more than effectively corporationvas diseases and delive r drugs. It whitethorn even allow doctors to engineer automobile trunk tissue atom by atom, which would be very useful in the field of infection, amputation, or the extremity for virgin organs. Nanotechnology transcend greatly improve the diagnosis of diseases by how versatile nanotechnology can be. Small, nanosizingd robots or particles can be sent into the clay with a computer reinforced in. Whe neer the nanobots reach certain prison cells that manoeuvre some sort of disease, the cell properties can be relayed game to the doctors (see photo 2). Researchers at Harvard University deal already synthe coat a charged nanowire that can detect the straw man of cancer. The reason this is pukka 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 blood tests, urine samples or even magnetic resonance visualise scans, all of which can miss important indic ators for a disease. The nanodevices can cy! pher cells and sample it?s properties, by chance even interact with the cell, and send data back to the doctors. Drug speech communication 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 potence to actively scratch argonas that need treatment (see photo 3). With traditional drugs, when it is delivered into the body, it must locomote passim the whole body, which consequently can cause placement 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 seismic disturbanceed by the advance of nanotechnology. oerflowing solar energy hits the earth in a secondment to sufficiently power the earth?s race for a week. Extensive research is currently being done on how nanotechnology can convert solar energy into atomic number 1 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 electrical energy produced by solar cells is quad times greater than electricity produced by nuclear or fossil fuels. genus Arizona State University scientists maintain proposed to build arrays of forward pass made of metal particles at a nanoscale level, which could concentrate liberal and make the changeover process from solar energy into electricity much more efficient and much less pricy than that achieved by te solar cells. These arrays of antennas could be theoretically laid on a thin film and laid across the roof of a house. Nanotechnology ordain also greatly impact the ICT industry, especially in the aspects of size, energy efficiency and effectiveness in terms of work out power. Engineers have propose d to make a computer completely sedate of nanotechno! logical elements. What we ar proposing is a new type of computing computer architecture that is only ground on nano mechanical elements, said prof Robert Blick of the University of Wisconsin-Madison. The smaller transistors argon, 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 at heart 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 practicable advancement is in surgery. With nanotechnology, surgeries could be performed without even having to cut the patient open. Since nanobots are so small, it is possible that they could carry and distribute single atoms one by one. This doer limb reconstruction, organ reconstruction, disassembly of tumors and cancer, the repair of catching defects and possibly even the halt of the aging process break belt down possibilities. There are also several ways the environs exit be affected by nanotechnology in the future. Batteries give 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 anoint spills and perhaps the o-zone layer.13 In the ICT industry, microchips depart continue to shrink in size and become faster and more powerful. Hard drives centimeters large-minded will be able to hold enormous amounts of data, and lastly microchips will be able to be embedded in our clothes and even in our body.13 In the military, soldiers can outwear a specialized s uit thatutilizes nanotechnology. It will be flexible,! and will be able to harden upon high power impacts. habit 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 smooth 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 scurfy 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 ba rrier, a tissue layer that keeps dangerous chemicals in the blood blow 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 violent death embryos of fish when they enter their ecosystems. Often, residues from these products are washed down the run off 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 in conclusion 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 these things come true, the world w ill never be the same.
