Advantages And Disadvantages Of Nao Silver Water

These changes can include how the immune cells function. By one reducing the natural killer cells and T cell cytotoxicity or by impairing the B cell function. By affecting these cells it can have dire health consequences like weakening the immune systems defense.

However, only experts like scientists and researchers who studies on the said topic have conceptual ideas about nanotechnology, about the advantages and disadvantages of the up and coming field of science. The founder of nanotechnology, Eric Drexler, said that his discovery can solve the many problems of society such as the lack of food, medicine, energy, and power. Professor Therese Rosbero, a lab professor in DLSU-Manila, stated that nanotechnology is a field of science in which other products of science such as biology, chemistry, physics, and medicine are applied all at the same time. She said that nanotechnology is composed of nanoparticles which are too small to be seen by the naked eye (Personal communication, 2015). On the other hand, most of the people in the society have zero to no knowledge about the inner parts of nanotechnology. At the early ages of nanotechnology, the public’s perception about nanotechnology is all about optimism and excitement as it poses potential life changing benefits (Priest, 2012). However, that perception of the people about nanotechnology changed as the once hidden properties of nanotechnology are slowly showing their capability to be harmful and less beneficial to society. Even though most of the people do not know anything about

Nanoparticles (1 000 000 times smaller than a millimetre) are manifesting to be a great success in nanomedicine’s discovery of supplementary methods of fighting against superbugs. At the University of Colorado, researchers have utilized nanoscale quantum dots, which are “miniscule semiconductor particles with specific light-absorption properties, to kill drug-resistant superbugs without harming the surrounding healthy tissue,” (Nagpal, 2017: para. 2). Nanoscale quantum dots that are activated by a light source perturb the balance of chemical processes in threatening bacteria that would kill them.

The article, Nanotechnology in the Military by Will Soutter, discusses the many ways in which the government is investing in nanotechnology research for military use. The article points out that nanotechnology is something that many countries are starting to spend large amounts of money to fund research on ways to use nanotechnology for military advancement. The main focus for military advancement through nanotechnology would be better medical care and better clothing for protection and to communicate. In the article the Ministry of Defense predicts that nano-bots could soon be used to help with medical care. In addition, communication devices could be nano-enhanced by 2030. Researchers are looking for ways to use nanotechnology to improve

The purity of the ingredients is essential for making true colloidal silver, for impurities will transform the solution into a different substance. Even the minerals in spring water will undergo unpredictable chemical transformations,

“This work has led many other investigators around the world to study this nanomaterial, but we were one of the first groups to study these nanoparticles in a biomedical context.

Antimicrobial coatings/particles are becoming increasingly commonplace which is overall detrimental. Antimicrobial coatings are a coating that is applied to a surface that either kills or inhibits the growth of microorganisms. This has various applications in hospitals, industry, and at home. The two most common functions of antimicrobial coatings are to prevent illness from pathogens and prolong shelf life of products by inhibiting the growth of mould. Antimicrobial coatings are ground-breaking and can save lives; however, problems can arise from the overuse of them. The biggest risk of these particles is that the bacteria we want to eliminate will develop a resistance. The overuse of these particles could also be causing harm to the

In the 21st century, human and technologies are inseparable. In past decades, there has been an astonishing amount of development in modern world’s technology. Nanotechnology is one of them. This technology is based on nano-scale and it can be used in many different areas because of its small sizes. (Metchis). However, there is a huge amount of uncertainties on the hazards of nanomaterial due to lack of research in this field in real world applications. There is a lot of things that need to be study on this technology. For this technology to be considered fully developed there is an immediate need for a balance between a free and unregulated market with some involvement from the government because both systems have its own strengths and weaknesses that will be discussed further.

Nanoscience is the study of objects measured in nanometers. To give a better perspective of size, one nanometer is one-billionth of a meter, or about eighty thousand times smaller than the diameter of a single human hair. A particular application of nano-materials in nature is the use of nano-finger tips which allow geckos to walk on walls. The gecko adhesive system incorporates one million foot hairs or setae in on each finger. One hair or seta contains a thousand of spatula tips which allow the geckos to attach to the wall. Synthetic nano-materials can be produced which exhibit strong adhesion effects similar to the gecko nano-finger tips. There are already many nano-tech products on the market which utilize synthetic nano-materials.

The chemical synthesis methods of ZnO nanoparticles like chemical precipitation, hydrothermal method, and pyrolysis, chemical vapour deposition, and so forth result in the presence of some toxic chemicals adsorbed on the surface. These substances may have adverse effects in medical applications. There are some reactions in these chemical procedures which require high temperature and high pressure for their initiation while there are some reactions that require inert atmosphere protection or inert conditions. Some chemical methods also involve utilization of certain toxic matters such as toxic template, H2S and metallic precursors [M.Hudlikar, et al, 2012]. The chemicals used for synthesis

Nanotechnology is the gateway to near limitless possibilities for the human race. It opens the window to a new realm we previously have never experienced-- Nanotechnology is a branch of engineering that deals with the manipulation of atoms at the molecular level. The Institute of Nanotechnology in the U.K. expresses it as "science and technology where dimensions and tolerances in the range of 0.1 nanometer (nm) to 100 nm play a critical role”. Once automated, the nanoparticles will infiltrate every aspect of our lives- from medical, engineering, biomaterials energy production, to name a few. Practically everything we use today could be replaced by nanomaterial in some way, and it even has the capability to create new materials.

At the beginning of new millennium, we can see tremendous progress in developed & developing countries and noticeable advancement in use of technology in each and every sector. In this era, science & technology play a keen and vital role and also became a dominant key factor for development of a country. Therefore, countries are striving hard to diversify their economies through the development and adoption of advanced technologies like Nanotechnology.

Second, nanosilicates, which are incorporated into a matrix of gelatin, can interact with polymeric chains. This will have a positive effect on certain physical, chemical and biological characteristics. [Janet R. Xavier et al. February 2015]

Nanotechnology is one of the most advanced and well reputed branches of modern sciences. Nanotechnology is handling of matter at the atomic or molecular level. Scientists from all over the world are now considering forthcoming effects of nanotechnology on human and environment. Nanotechnology is likely to be crucial to the 21st century scientific and medical advancement and its developments will be determined by the collective hard work of natural, physical, medical, engineering and related sciences. The materials in Nano scale can show different properties compared to what they exhibit on a macro scale. A nanoparticle by definition is, an ultra-refined particle that has all the dimensions in the Nano range i.e. from 1nm to 100

Silver is bright and shining metal known to mankind from ancient times. From ancient time’s human civilization are using silver for jewelleries, utensils, weapons, coin, medicine, water containing tanks. From early days silver is assisting the immune system when it was plentiful available in dissolved metallic form in water[1]. In periodic table it is placed at 47th position near to heavy metal.it is a transition metal. It has atomic weight 107.8. Silver has good metallic property like malleability, ductility, thermal conductivity and electrical conductivity [2]. Silver exhibit the excellent anti-microbial property. After the development of nanotechnology we are using silver extensively in various area. Now a day we use silver nanoparticles (AgNPs) instead of metallic silver for many of daily uses. It is seen that AgNPs is highest degree of commercialisation among all the Nanoparticles in medical and health sector. There are numerous uses where AgNPs are used like in cloths, medicines, disinfectants, tiles, surgical equipment, and silver coated bone prosthesis. Nao silver is also used in room spray, paints and laundry detergents. Many manufacture using nano silver in washing machines and refrigerators. Silver coated or vessels are used to preserve water and wine mainly during long voyages.
