The microfluidic system has been designed to detect microamounts of specific substances as well as distinguish which readings are not significant or technically called noise. The microfluidic system is also used in the molecular screening of diseases. Today, nanotechnology is much appreciated because of several advantages the revolutionary technique is presenting. Firstly, the surface ratio that is essential in both electronic and medical fields is much easily attainable using nanoparticles. Secondly, nanoparticles provide the opportunity of reaching small places, which cannot be reached by bigger particles, thus the transport of molecules is simpler using nanoparticles.

In addition, nanoparticles are easier to handle when flow rate are needed to be controlled in experimental setups, mostly due to their small size. Nanoparticles are also easily labeled for tags that are important for detection hence there are now currently an endless list of ways of detecting these tiny particles at different settings, be it in the electronic or medical field Hahm and Charles, Another interesting product that comes from the emergence of nanotechnology is the creation of microreactors, which serve as better versions of the original and bigger reactors. Microreactors serve as tiny venues for the collision and interaction of molecules at a smaller scale and volume. In the medical field, several drug delivery systems have been designed that are aimed to transport substances to specific sites in the human body and prevent any cross-reaction with the rest of the human body.

An interesting example is the use microlipid systems, which are similar to membrane containers that can travel through the circulatory system through intravenous injection. These microlipid systems, or micelles, commonly contain substances or even deoxyribonucleic acid DNA that may correct any defective gene that may exist in the patient. For cancer patients, microlipid systems may be administered to deliver anti-cancer drugs that should only react with cancer cells and leave the rest of the normal cells in the body alone. It is known that earlier medical therapies often present with a lot of side effects to the patient.

We could also have more grassy areas that the water can absorb into, too. There were a few topics that I learned that I did not know before. Around the globe every minute a child dies because of water-related disease, Women spend hours walking to collect water, it has been estimated 1 in 9 people lack access to safe water, hospital bed spaces are occupied majorly people related to water-borne diseases. Clean water is essential for both mental and physical development. Lead in tap water causes many birth defects. Thousands of contaminants are present in tap water which are even poisonous. For every spent on water and sanitation there is a double return to the economic. Possible chance that this concern isn't covered soon, it will have tremendous affects for us too be carrying on with a solid way of life overtime as our activities will be irreversible.

In this way, continuing to spread destructive toxins all around is intolerable conduct towards our environment. Water Pollution is a huge environmental problem that has serious effects on marine habitats, animals, and water quality. BP1: The world's marine habitat has been getting worse because of how bad the pollution has gotten. This quote explains how most of the water pollution is caused by human activity. IPL Nanotechnology Essay. Nanotechnology Essay Words 4 Pages. Nanotechnology Essay Nanotechnology is a part of science and technology about the control of matter on the atomic and molecular scale. Nanotechnology is one of the newest science technologies until now. It is used in many applications.

For example, nanotechnology can be used to link elements of Carbon together so that they form a diamond. However, nanotechnology can also be used to help solve some of our global problems. One of the problems facing our earth is water pollution. Water pollution kills more than 6 to 8 million people per year. Water pollution affects people around the world. According to the website conserve-energy-future. According to the study, the water filter is designed with nanomaterials that work together to remove microbes from the water. In addition to this technology being used in India, another company in Oregon, USA is selling a filtering system. This company uses "five photochemical processes" that can break down the pollutants from the water.

This company hide their filters as lily pads to make the process look beautiful and natural. Without being affect by these positive efforts to clean water so that everyone has access to drinking water, there is some worry about the effects of nanotechnology on the environment. However, more research and experimentation will be done to improve the quality of water. Show More. Pollution In Haiti Words 3 Pages Clean water is just the beginning to a brighter, cleaner and healthier. Among the active fungi that were reported to produce nanoparticles; Rhizopous oryzae produced nanoparticles intracellularly of gold Das et al. However, F. oxysporum produced nanoparticles of silver of 5—15 nm and nm in diameter extracellularly Ahmad et al. Many other fungi were approved for their productivity of nanoparticles of different metals either extracellularly or intracellularly including:.

Phoma sp. Chen et al. Shankar et al. semitectum Sawle et al. solani Ingle et al. Singh et al. Many recent reports have shown that production of nanoparticles by fungi are could be affected by various condition of temperature, biomass weight, time and pH Balakumaran et al. Husseiny et al. Narayanan and Sakthivel approved that incubation at 27 0C for 72 h with 7 pH and 10 g of the fungal biomass and 1mM concentration of AgNPs were considered the optimum conditions for production of AgNPs from AgNO3 by fungi. Researches showed some variations in the characteristics of the biosynthesized AgNPs by different fungal species. These variations could be due to the source of fungal isolates or strains and types of medium Devi and Joshi, ; Roy and Das, When Alam et al. This because this medium contains essential carbon and nitrogen source along with other vital macro and micronutrients such as magnesium, sodium, calcium, potassium, iron and zinc which are vital for fungal growth.

Nowadays, application of AgNPs confirmed their effectiveness in treatment of cancer, bone implant, anti-inflammatory and their biocidal activity against many bacteria and pathogens Husseiny et al. It is expected that the large surface area to volume ratio as well as high fraction of the surface atoms of the nanoparticles increase their antimicrobial activity as compared with bulk silver metal Joy and Johnson, Moreover, the small size of the nanoparticles facilitates their penetration inside the cell. Additionally, excellent antibacterial properties exhibited by AgNPs are due to their well-developed surface which provides maximum contact with the environment Mitiku and Yilma, Recent research approved the antibacterial activity of the silver nanoparticles against many bacteria especially those having the capability to cause severe disease for the human such as Salmonella enterica, Enterococcus faecalis, Streptococcus, Proteus mirabilis, Staphylococcus aureus, Escherichia coli, Staphylococci and Pseudomonas sp Devi and Joshi, ; Shelar and Chavan, ; Muhsin and Hachim, ; Madakka et al.

However, shape, dimension, and the exterior charge as well as the concentration of the AgNPs are important factors that affect the antimicrobial activity the nanoparticles against the tested bacteria Madakka et al. Devi and Joshi approved the antibacterial activity of AgNPs comparing with erythromycin, methicillin, chloramphenicol and ciprofloxacin agents Staphylococcus aureus, Streptococcus pyogenes, Salmonella enterica and Enterococcus faecalis. They showed that the diameter of inhibition zones obtained by the silver-nanoparticles, with nm in diameter, were more than those obtained by the antibiotics. Shelar and Chavan, showed that Bacillus subtilis and Staphylococcus sp were inhibited by silver nanoparticles with diameter of nm in very close pattern to the standard antibiotic streptomycin.

Based on the above-mentioned information, we assume that fungi as bio-factories for the biogenic synthesis of the silver nanoparticles are very interesting during eco-friendly and safe technology, also for future application as antimicrobial agents.

At the moment, the very existence of nanomaterial and nanotechnology is a variety of opinions, attitudes and creates myths. One of the most popular explanations for the ordinary inhabitants is as follows: nanotechnology is a technology for manipulating matter at molecular and atomic level. Like any other phenomenon, the nano has created two opposing views: The first is that nanotechnology is our future, our development, and the second states that the nano is just a temporary whim of scientists involved in taking money for their experiments, some fashion in the scientific world. But both these views are, in principle, wrong. With regard to development, nanotechnology is truly a new level of scientific knowledge that can bring real improvements in terms of production technology.

However, at this point in some areas of science or the application of nanotechnology products could be harmful or not very convenient. Nanofood is food created with the help of nanotechnology, for example, in processing plants or housing, or creating the package. Such foods contain modified molecules, which give food to their unusual properties: for example, they can glow in the dark or unusual colors. With regard to benefits, there it is the main argument in favor. The point is that nanotechnology in the food formation improve its nutritional properties and do better. These products ideally suit to developing countries, as it is relatively inexpensive. Developed countries are also seeking to obtain such a useful and valuable product, because it used to monitor their health and development of nanotechnology may give the food a large number of vitamins and reduce the content of harmful substances in it Rogers, Here, the development of nanotechnology is everywhere.

Scientists apply their development in various fields of medicine. Not so long ago, experts from the University of Michigan have created a completely new version of a vaccine against anthrax, of course, with the use of nanotechnology. They entered one of the pathogens in a particle, consisting of water, alcohol, soybean oil and some others, and this emulsion injected into the noses of test mice. As a result, the animals develop immunity to the disease. Advantage of such vaccine is that it may be introduced into an organism affected by spraying, without the syringe, and unpretentious in storage: it can be at room temperature. Applied nanotechnology is used to strengthen the prosthesis. Scientists have invented nanowire, which strongly reinforce titanium implants.

These prostheses are used in medicine to replace damaged bone. But muscles can not be firmly consolidated in the smooth surface of conventional titanium implant, so it had to change, and thus, once again from outside to invade the body. However, the coating of implants with nanowire titanium dioxide allowed solving this problem. Specialists of Schools of Pharmacy have established a three-dimensional model of cancer cells, coexisting with normal healthy cells. They were able to enter into such a model of special nanoparticles that are suitable for drug delivery. In the experiment modeled the interaction of cancer cells from normal tissues, which is defined by the position of the tumor within the brain.

According to scientists in the future, such studies may lead to effective therapies for brain cancer Uldrich, Scientists have created nanoparticles that can detect and show the amount of hydrogen peroxide in the body it is known that cells in the early stages of the disease produce hydrogen peroxide. Such particles may some day be used as a universal diagnostic tool to detect any disease in its early stages. The synthesized nanoparticles in further studying this problem can help understand the role of hydrogen peroxide in the course of disease, as well as become a kind of diagnosis. Nanostructures have their specific properties. For example, nanoparticles of ceramics used in the preparation of paints for cars, which are resistant to all kinds of scratch, gold nanoparticles have a reddish tinge, nanoparticles of silver, to protect people against infections.

Typically, these particles are created chemical method and contain a lot of impurities. Attitudes to such technologies in the world in general are ambiguous. In Europe, nanotechnology is considered as a basis for the future of medicine, energy, information and environmental technologies Uldrich, Experts believe that nanotechnology will become the driving force behind the next industrial revolution, and will change our way of life. Research and development of nanotechnology are in a state of recovery in the pursuit of original and useful things, and then comes off as a tailor-made, very little is done to ensure that ensure public and environmental safety. Dollars invested annually in research and development of nanotechnology is approximately 3 billion dollars, representing approximately one-third of the total number of public and private investment in nanotechnology in the world, — stated in a press release the International Center for Scholars Woodrow Wilson Washington.

Nanotechnologies offer great potential benefits in improving almost all types of industrial products: computers, cars, clothing, food, medicines, batteries and much more. The growing number of research reports and government cautions that created nanoparticles may be hazardous to human health and the environment, even though it was a bit of research about their toxicity, — said in a recent report of Vital Signs Worldwatch Institute Worldwatch Institute. Nanotechnologies comprise a wide range of technologies to control the structure of matter at the level of atoms and molecules. Nanometer is one billionth share of meters, width of 10 adjacent hydrogen atoms, the thickness of a human hair is approximately 80 thousands of nanometers.

At a microscopic level, matter behaves differently than in our daily lives in this world, which dominates the classical physics of Newton. In nanoworld «properties of matter are determined by a complex and rich combination of classical physics and quantum mechanics», — said in an exclusive online edition of Scientific American for January Also, large quantities of tiny nanosubstance can have enormous power because of their greatly increased surface area of the relationship to the volume. Under the complex of developed nanosubstances it is meant that their impact will depend on more than just the chemistry, only one microscopic nanoparticle size could allow them to more easily penetrate and infect human organs.

The fact that the substance of nanoscale may have extraordinary properties — properties that is inconsistent with the «capital» physics and chemistry — can be a potential threat. Researchers are not sure how to safely work with new nanosubstances, the nanocompanies just do not know how to create safe products, and public confidence in these new technologies, risks being undermined, head of developing nanotechnology Project on Emerging Nanotechnologies. According to Maynard, there is a need for international coordination: «It should find ways to harmonize research, sharing the costs and sharing of information between countries and economic regions» Jones, Maynard pointed out that the industry has a commercial purpose which is to sell products, and the results of their research are not always public.

The most viable alternative system for research in industry is the system pursued by the Government. Andrew Maynard — Chief Scientific Advisor of developing nanotechnology is an initiative organized by the Woodrow Wilson Center and the Pew Charitable Foundation in , he created and July 19 in Washington, introduced a new report entitled «Nanotechnology: a strategy for research to examine the risks associated with it». According to the report, the efforts made by the Federal Government of the United States are inadequate. In the study of the impact of nanotechnology on the environment, safety and health, there is no strategic direction and consistency.

This report is the first attempt to propose a draft systematic study of the potential dangers of nanotechnology. The report presents the requirement of two important developments: 1 Change of direction and funding for studies of risk in favor of federal agencies with a clear mandate to monitor. According to Vital Signs , serious concerns are not limited to security issues and the impact on health: should be explored and more profound social and ethical implications. Scientists argue that the world stands on the threshold of unprecedented change: new economy, almost human immortality and, in general, the transition to a new civilization. In theory, nanotechnology can provide the physical immortality of man due to the fact that Nano medicine can indefinitely regenerate cells die.

According to the forecasts of the journal Scientific American in the near future will be medical devices in the size of a postage stamp. They have to put on the wound. This device will hold a blood test; will determine what medications should be used. Nanotechnology can make a revolution in agriculture. The molecular robots would be able to produce food, replacing agricultural crops and animals. For example, it is theoretically possible to produce milk from grass, bypassing the intermediate link — a cow. Nanotechnology can also stabilize the environment. New types of industry will not produce waste, poisoning the planet. It should be noted that the global cost of nanotechnological projects now exceeds to 9 billion dollars a year. The share of the U.

now accounts for about one-third of all global investment in nanotechnology. Other major players in this field are the European Union and Japan. Research in this area are also active in the former CIS countries, Australia, Canada, China, South Korea, Israel, Singapore, Brazil and Taiwan Jones, In addition to the pros this branch of science has a number of disadvantages. Terrorists and criminals who obtain access to nanotechnology, can cause considerable damage to society. Chemical and biological weapons will be more dangerous and less of it will be much easier. Firearms will be much more powerful — and homing bullets. Aerospace technology could be much lighter and better constructed with minimum or no metal, which makes detection of radar will be much more complicated.
