The Medical Uses of Nanotechnology

Medical uses of nanotechnologyTechnology is taking more steps and making changes to the way we do things every day. It has improved the way things are done, and how easily they are accomplished. Nanotechnology has made its way into the medical field, making certain processes easier to be accomplished, and better than ever before.

The history behind nanotechnology

Nanotechnology first became popularized in the 1980s. It was then that the idea of building machines on the molecular scale began to be explored, looking at electronic products being built even smaller than a cell. These technologies were explored over the next few years, developing nanotechnology closer to what it is today.

The meaning of nanotechnology has expanded since it was first thought of. It is now often referred to as general-purpose technology. The advances that will be made in this field will impact almost all the other fields of study, including the medical field.

What this means for medicine

Studies have started in the medical field using nanotechnology. This is done by manipulating the components of cells, virus, or structures of DNA using tools small enough to do the job. The use of small electronic devices such as robots, and tubes has become critical for nanotechnology in the medical world.

In 1987, reports were designed outlining the future of the Human Genome Project. In 1990, the project was put into motion. This process set forth with the goal of mapping out exactly what makes up the DNA of a human, and finding where mistakes may be made in certain people’s codes. This knowledge is crucial for finding medical problems, and using nanotechnology to fix them.

With nanotechnology, treatments for patients directed at manipulating the DNA will be designed specifically for each individual. The technology used here is designed to stretch out the DNA, and examine it piece by piece, determining what each patient needs.

Using DNA fragments, scientists have designed a robot on a nanoscale that is still being perfected. This small device will be able to move along the thread of DNA, controlled by scientists until finding the piece that needs to be fixed. This process will be more efficient than some other methods, correcting the problem from the core rather than dealing with the symptoms.

Bringing it to the public

Although nanotechnology has made many advances in the medical field, it still has a long way to go. The processes are still being discovered, tested, and perfected. Production is slow and expensive at the moment, but as soon as the methods are further developed, this form of medical intervention will become a reality for many.

At the point that the cost and effectiveness are improved, it will become essential to convince the public of how safe the procedure is, and how accurate it will be. The beginning stages will be most difficult, but once the positive effects are seen, will be easier to spread further.

Nanotechnology has made huge strides in the past thirty years. Although there is still much to learn when it comes to the process, the medical field will see it implemented in their sphere sooner rather than later. These technologies will help keep people healthy, and further determine why certain medical issues occur.

Nanotechnology and Electronics market

This article began by noting the recent hype in the electronics market, both positive and negative, that has surrounded nanotechnology and appears to be growing less extreme: today, rosy projections of a “trillion-dollar” nanotechnology based electronics market in 10 years or apocalyptic predictions about a “Faustian bargain” or a “Pandora’s box”1 are heard less often. However, while the hype may have slowed somewhat, it is still there. Growing public awareness combined with the complex, diverse nature of the technologies that are commonly grouped together under the heading of nanotechnology virtually invites misunderstanding, if not actual misrepresentation. For example, in 2010, a respected journalist wrote a series of stories for AOL News with the title, “The Nanotech Gamble: Bold Science, Big Money, Growing Risks,” that faulted the U.S. government’s performance in identifying and protecting the public against alleged health hazards posed by nanotechnology. One interviewee asked rhetorically, “How long should the public have to wait before the government takes protective action? Must the bodies stack up first?” So stinging was the piece to the National Nanotechnology Initiative (NNI) and the National Nanotechnology Coordination Office (NNCO) that the director of the NNCO felt compelled to issue a formal rebuttal. According to the rebuttal, the author “takes an alarmist perspective,” “uses irrelevant examples,” and fails to balance the risks against the benefits of nanotechnology. As some observers have noted, the debate over the AOL News article (which was still simmering when this report was written) is at best a distraction from the research that needs to be done. Business, academia, the media all have an incentive to attempt to cash in on nanotechnology in the electronics market. Various manufacturers have tacked “nano” onto their products and processes, whether or not they deal in nano-size elements, in an attempt to boost sales. Companies that have nothing to do with nanotechnology have “nano” in their names to make them sound more technologically advanced than the competition. Some academic researchers worry that the nano buzzword is being misused to bring in research dollars for dubious technologies and applications, at the expense of legitimate research. Hype inevitably carries with it the risk of a backlash, because it can create unrealistic expectations for nanotechnology. Then, when expectations are not met, people tend to withdraw or worse turn oppositional. A blog entry on The Bespoke Investment Group’s website observed that: “Back in the ‘good ‘ole days’ of the mid-2000s, investors were riding a bull market wave and looking for ‘the next big thing.’ One of those ‘next big things’ was nanotechnology. Ever since the collapse began in 2007, however, the nanotech craze seems all but forgotten. As a result, legitimate nanotechnology products and applications are hurt along with the rest, as funding and markets dry up. The dot.com boom and bust provides a cautionary example of the dangers of hype, but nanotechnology has a more tangible nature because it is a set of technologies. This report takes a realistic look at the nanotechnology field in the electronics market and tries to provide a road map to the technologies and applications that are most likely to be commercialized in the next 5 years.

Nanotechnology applications in construction

 

Abstract In researching the issue we noticed that nanotechnology is a wide area about different concepts and applications that have found different researchers, we read and we think some of the most important issues, focusing on nanotechnology applied to advances in the construction .   INTRODUCTION The following essay is to analyze nanotechnology, examining its general application to the industry of construction, and environmental benefits it can bring nanotechnology. It also aims to study the impact of nanotechnologies in different parts of the world, highlighting issues such as nano science and nanotechnology, materials nano-structured architecture and nanotechnology, nanomaterials applied to the construction, nanotechnology in other countries in nanotechnology field of materials, acceptance for environmental nanotechnology relating to construction of the care of the environment , among others. 1 Roughly speaking, one could say that nanotechnology has the ability to develop or produce materials, devices or systems , by monitoring its field to scale gauge.   Thus, their physical and chemical properties can be modulated systematically by varying the size, facilitating the design of new materials with a lower consumption of natural resources . The truth is that nanotechnology will radically change not only the use of materials, with the new generation of nano materials, without subjection to the laws of physical mechanics traditionally, but also how to design and build, in fact, no construction without nanotechnology.   DEVELOPMENT OF CONTENTS   We should note that the terms Nano Science and Nanotechnology refers either to the development of science and technology that has been occurring over the past two decades and has allowed the construction and manipulation of materials at nanometric scale. The prefix nano, the Greek nannos (very small), turned into Latin as nanus, meaning dwarf. This prefix is applied to indicate that is a billion times smaller than the reference unit, whether of length, mass, time , etc.. The following chart can analyze size relationships to better understand   A. Nanostructured materials There are currently metals whose resistance is five times greater than their natural counterparts. There are materials that change Color depending on the spectrum of light is applied to its surface, and in some cases become completely transparent, have been built semiconductors 300 times more efficient than those used in electronic advances with so many conventional then we explain is the difference between the common materials and the aforementioned, well when comparing two pieces of material with a volume identical, for example, two solid cubes of copper of a cubic centimeter, the difference being that inside the piece of common material, the molecules are arranged in grains with typical populations of billions of atoms, whose granular size ranging from microns to millimeters in diameter. In the nano-structured piece of material, molecular grains have a maximum size of 100 nanometers in diameter with granular populations of less than tens of thousands of atoms. In other words, nano-structured grains are a thousand and one hundred times smaller than those of a common material, and also within the same volume have the 0.001 percent of atoms. This means a saving incredible material inside each piece of material nano-structured and, therefore, a lightness in weight can be a thousand times greater than normal. This physical distinction can also get priorities and new features, unique and amazing never before been seen in the common materials   B. Nanotechnology in the Field of Materials Some of the amazing applications of nanotechnology in the field of materials is for example the development of a painting with self-cleaning properties and anti-graffiti. There are also thick and nanometer coatings protect steel from corrosion , or ceramic cups WC for having a completely smooth surface to gauge scale, which implies that stays nice and clean each time you press the pump cistern without subsequent cleanings   C. Nanomaterials applied to the construction Nanotechnology can develop stronger materials than steel, with only 10% of its weight. Nanotechnology has already been applied in the construction sector in the manufacture of steel and concrete more resistant, with improvements in infrastructure and construction. Polymers have been developed members of protective barriers in the roads repair their own damage caused by the collision of vehicles. Similarly, repair cracks and holes in concrete and asphalt, without human intervention, that is why we will discuss further these points:   Road construction 6 The application of nanotechnology in building roads and will also be identified and repaired automatically, without human intervention, gaps and holes in the asphalt or concrete, and making signals of traffic that are cleaned themselves . Nanotechnology is used to make steel and concrete stronger. Also for security vial. For example in parts of the United States have been placed nano sensors to monitor the condition of its bridges and detect any abnormalities or risks .   Concrete additives nano The traditionally built concrete itself, but micro- structure complex owes its properties, in large part to the CSH gel matrix cement, which continues to be a nano-structured materials with modified properties for a network of pores and micro cracks, which size can vary from a few nanometers to millimeters. knowledge of nano-phase structure and allow the gel to open the range of products derived from cement with multifunctional properties.   GAIA Another nano additives for concrete, in this case does not disclose controlled materials atom by atom during the process of manufacture, the new techniques have been used only during the development phase of the product . 7 The company Cognoscible Technologies has entered the market Spanish a new concrete additive named Gaia, which would replace the traditional micro silica, and offers the same price many advantages over it. The additive Gaia allows you to save up to 40% cement.   7 “A liter bottle of Gaia equals a whole barrel of micro silica, extra cement and knew plasticizers. What used to take a beam of 2 meters thick to properly hold the bridges, now only requires 75 cm. If before had to wait 28 days to reach high resistance of 80MPa, now just have to wait 1 day. prestressed beams that once required 3 days and be cured with water vapor to be ready, now only require 1 day and not need water. The challenge arose when the largest underground copper mine in the world, El Teniente, located in Chile, called for an improvement of micro silica used in concrete.   It created an additive that worked not on the micro particles of silica, but on their nano particles, with the aim to exploit the material properties at the nanoscale offers. The new product, called Gaia, is the first replacement of silica fume additive that is sold in liquid, which disappears with the generation of silica dust, dangerous for the health of operators. This feature, among others, allows Gaia is capable of being used in processes that meet the environmental standards.   In Architecture 8 Just looking at the future prospectively with some objectivity, and huge amounts of hope, we think of wonderful and unusual solutions constructive. In the immediate future, we could conceive five times higher buildings that will support five times higher loads, which were more slender structural sections, and that in an earthquake is not fractured. Would imagine buildings whose walls and floors will change color as the sunlight changed his tone. Then we would think that would be transparent partition walls in the day and opaque on the night. We would see two-story houses, easily towed by a small vehicle, to change location. Find in any supermarket large structural components, to price cheap, light enough for a child of four years could carry.   D. The nano technology in other countries Around the world all countries are stepping up research of nanotechnology using it in different types of applications such as company Skanska plans to build concrete walls that break down the gases expelled by the exhaust from vehicles in road tunnels, in addition sidewalks that clean the air in cities.   The graph below shows the spending, in millions of euros for 2003. Figure 2. 9 public expenditure of European Union in nanotechnology As you can see the most developed countries are the most invested, but taking into account as a special case in Spain and almost no public funding of nanotechnology. We also have the graph of investment finance in all countries around the world.   igure 3 spending worldwide. In which we see the same special case of Spain in the bottom, watching this it follows that Spain will suffer if it fails to act timely on investment , the endemic problem that began in the First Industrial Revolution and culminated in his utter and total dependence on technology. This is the opportunity, therefore, not to be missed Spain to board the train and called Second Revolution Industrial. E. Acceptance to the environment linking nanotechnology construction with the same care We must ask what benefits the environment and manufacturing production of nano materials applied to the construction, and whether they will have less environmental impact than current building materials. The truth is that, without diminishing the risks that may involve nanotechnology, initially there are multiple advantages of a proper use of such technology:   • First, allow a reduction in the use of resources natural, since the amount of material used in these processes of production (which save raw materials and energy resources) will be minimal • Second, a consequence of this, will reduce the generation of waste As disadvantages, it is necessary to mention that there are insufficient data to judge the toxicity of nano materials and most likely not all will be biologically inert. At this potential environmental impact , we must add the social impact of nanotechnology resulting in people who know almost their existence and its possibilities.   III. CONCLUSIONS At the end of this paper certainly takes the reality that produces breakthrough nano technology and can offer multiple and varied opportunities for development, and that is influencing other widely in research to improvements in all the senses exist. A very interesting point you make, apart from obviously nanotechnology is excellent progress, is the fact that not all countries can adopt either socially or economically this development and this will result in a very sad but true case of division technology around the world in which many of the countries like Spain where development will suffer.   REFERENCES   http://www.revistananociencia.ece.buap.mx/5nr2/11Espana20Nanotecnologia20korrigiert20bis201111.pdf http://www.construcgeek.com/blog/nanotecnologia-en-la-construccion http://www.imcyc.com/revista/1998/febrero/nanfeb98.htm http :/ / www.cognoscibletechnologies.com/es/ press / news / nanotechnology-divulgacion.php Arenas, F.: The environmental impact on the building.

Nanotechnology In Led Production

Nanotechnology is primarily the adjustment of a matter or many issues on a molecular scale. The concept of the technology has actually been announced since the 1960s, but significant r & d began throughout the 1980s. Its introduction to LED production is delivering quality accomplishments both in lighting remedies and for displays.
LEDs are the most energy-efficient lights solution on the market, because LEDs change the majority of power in to light. Still, about 20 % of the light produced by the diode is shed due the high refractive index of LEDs (a particular percent of the light is reflected back inside the diode and is not given off eventually). This rate often depends upon the components of the diode. To get this light otherwise shed within the diode, analysts and lately adopted by suppliers used nanotechnology and created microscopic gaps (roughly 400 times narrower compared to a human hair) on the surface of the diode, usually hundreds of hundreds of openings on a solitary diode.
Given that the intro of Nano imprint innovation to this process developing LEDs with nanotechnology it is more affordable and much faster compared to previous options The alleged Nano LED is a more highly effective and effective LED option, with absolutely lighter released. Likewise, besides lowering the optical reduction, recovered light cause much less heat accumulated within the diode. In this manner, LEDs can be stuffed better per various other, and also have an usually longer lifespan. An additional, fringe benefit of Nano-LEDs is their higher CRI, and a broader assortment of color temperature level.
A very early application of the innovation was not also in lights solutions but in tv screens, where nanotechnology caused a brand-new generation of LED Televisions. First LED televisions are not real LED remedies, they are actually LCD TVs with LED backlighting from the sides. With nanotechnology, LED TVs are created with a full array of LEDs, behind a panel of tiny or nano dots permitting light via sent out by LEDs. This way light is dispersed even more equally, giving the presented photo a lot more meaning, quality and level of smoothness. This innovation likewise enables the show to be thinner: the first TV produced with the modern technology is the LG LEX8, which is just 0.88 cm thin.
Nanotechnology delivers brand-new, interesting outcomes consistently. In the field of lights, among the latest news is nano-LEDs increased as cables. This modern technology was accidentally found September 2010, when chemists Babak Nikoobakht and Andrew Herzing experimented with increasing nano-wires flat. With the boosted density of the gold catalyst, the nanowires grew a nanowall, which electrons can flow throughout. Charged with electrical power the wires generated light, hence analysts named the phenomenon as nano-LED. This innovation will allow including lighting to tiny remedies, yet its full scale of capacities is unexplored.
In a similar way intriguing success of nanotechnology in lighting can be the remedies of Academia Sinica and the National Cheng Kung University in Taiwan, where professors implanted gold nanoparticles into leaves of plants, therefore developing a bio-luminescent red light. These bio-LEDs need further advancement, yet the purpose is to make trees giving road light along roads. Presumable the plants would certainly additionally soak up CO2 during the evening, which is an added level of photosynthesis.
Nanotechnology intendeded for producing further lights options is a promising future in the most non-traditional kinds of illumination. Biological illumination or organic illumination are both vital viewpoints in eco-friendly illumination, makings study for lower expense and much better executing LEDs crucial.

The world of Nanotechnology

The world of Nanotechnology

An impressive number of scientists from many spheres are today dedicated to the nanotechnology field. This is a whole new world of atoms and nanostructures, exciting but so small that we cannot actually see it even with a microscope. The science of nanotechnology is so new and even scientists are not sure in which direction it will take them. There are speculations that this new field of science will cover all spheres of science – from medicine to production of diamonds. Before we go deep in the world of nanotechnologies, we should first try to imagine the units and their measures. For example, a centimeter is one-hundredth part of a meter, the millimeter is one thousandth of a meter, while the micrometer is one millionth of a meter. Compared to the nanometer, these are huge. The nanometer is one billionth of a meter, which makes it smaller than the length of the visible light. Even so, the nanometer is larger if compared to the atom, which is the building material of the entire universe. We are all made of atoms, everything else around us is also made of atoms. The cells in our bodies play the role of nano machines. Or in other words, we can use the nano atoms to make anything that we want.

Nantotechnology can be used in various fields of science including chemistry and biology, engineering and physics, and so on. Thanks to it, today the different disciplines can communicate easily with one another. In general, the nanotechnology cannot be understood without a good background and knowledge in various sciences. Even so, the nanoscience can provoke the scientists to start learning again how things work. Currently, they are making experiments with various substances at the nanoscale, in order to learn how they work and how they can be of use in different applications.

Nanotechnology is already applied in many products that are on the market. For example, scientists are using nanoparticles to improve our clothing. The manufacturers apply a thin layer of nanoparticles that give good UV radiation protection. Others use have nanoparticles to make stain-resistant clothing. Nowadays are also produced antibacterial bandages by using silver nanoparticles. Nanotechnology is also used in the production of sunscreens that do not give white marks on the body. Other companies are producing self-cleaning glass by using nanoparticles, which could be well applied in many spheres and production lines. There are also coatings that resist scratches, again thanks to the nanoparticles that are asses to the polymer coatings. Many new products that use nanotechnology come on the market every month. These could be cosmetics with deep penetration, fabrics that are resistant to wrinkles, liquid crystal displays, etc. All these products are quite tempting and exciting and they show us how the Nanotechnology can affect every aspect of our lives and impact our entire future. Of course, the first thing that has to be done is to develop nanoscopic machines that can produce more and more devices, various objects and useful material.

Response by NextRightGuy
Strictly speaking, nanotechnology is a discourse. As a dynamic field in rapid improvement across several disciplines and nations, the definition of nanotechnology is not constantly clear cut. But, it is nevertheless beneficial to begin with some definitions. “Nanotechnology” is often utilized with minor qualification or explanation, proving ambiguous and perplexing to these trying to expand an awareness of such tiny scales. This can be fairly puzzling when the phrase “nano” is utilised the two as a nickname for nanotechnology and a buzzword for client merchandise that have no incorporated nanotechnology (eg. “nano”- car and ipod). It is hence useful for the student of nanoscale science to make distinctions among what is “branded” as nanotechnology and what this word represents in a broader sense. Molecular biologists could argue that because DNA is ~2.five nm wide, daily life itself is nanotechnological in nature — creating the antibacterial silver nanoparticles usually utilised in existing goods seem nano-primitive in comparison. SI units, the global common for units of measurement, assigns the “nano” prefix for ten -9 meters, however in usage “nano” typically extends to 100 occasions that size. Worldwide standards based mostly on SI units provide definitions and terminology for clarity, so we will follow that instance although incorporating the flexibility and open-ended nature of a wiki definition. Our emerging glossary of nano-connected terms will prove useful as we check out the different discourses of nanotechnology.
