Nanotechnology in our lives; Is it true that good things come in small packages?
Throughout the years, the technology available has increased drastically. Technology has evolved from the things that were once seen as unbelievable and mindboggling, to common everyday devices and some of which are now a part of us. Thanks to technology we are able to examine and solve problems now that were only a dream to many scientists 25 years ago. As we have increase our ability to use these devices, the developments and progress in artificial intelligence and molecular technology have created a new form of technology; Nanotechnology.
Nanotechnology is basically “an extension of existing sciences” (M.H. Fulekar 2010), only at a much smaller, nano, scale. Nanotechnology is the understanding and controlling of matter at sizes of roughly 1 to 100 nanometers, smaller than a strand of human hair, which is nearly 80,000 nanometers thick. figure 1 Using nanoscale science, phenomenal engineering, technological, and medical ideas, it covers a whole range of various developments. Although it contributes to many areas of science, chemistry plays the most important role to its use and development.
This is the building of nanomaterials into defined, complex structures, atom-by-atom or molecule-by-molecule. Thus, chemistry forms a base for nanotechnology by providing tailor-made molecules and polymers. (3) All manufactured products are made from atoms. "The properties of those products depend on how those atoms are arranged. For example if we rearrange the atoms in coal, we get diamonds. If we rearrange the atoms in sand (and add a pinch of impurities) we get computer chips. If we rearrange the atoms in dirt, water and air we get grass." (5) Nowadays ...

...s to question what implications they may have on our health, as nanotechnology is a new type of science.
Nanotechnology may also allow us to create more powerful weapons which are very dangerous. Weapons are an obvious negative use of nanotechnology. By extending today's weapon capabilities by being able to create miniaturizing guns, explosives, and electronic components of missiles would be deadly. However, also with nanotechnology, armies could also develop dissemblers to attack physical structures or even biological organism at the molecular level.(9) "On the instrumental level, there is also the possibility of nanotechnology being used to develop chemical weapons and because they will be able to develop the chemicals from the atom scale up, critics fear that chemical weapons developed from nano particles will be more dangerous than present chemical weapons."
...e materials at the nanoscale might include new form of nanobase toxicity. The individuals working with large quantity of nanomaterials need to take appropriate measures to avoid inhalation and ingestion. However, scientists have found silicon o be good for the construction of nanorobots because of its unique properties; durability, flexibility and conductivity. However, silicon cannot dissolve in body fluids. In addition, in medical applications biodegradability is going to be challenge due to the foreign particles inside the body and controlled mobility.
Amandi Hiyare: Before forming my research question, I had a discussion with my research project coordinator “Lisa Pope” who told me that the Flinders nanotechnology research team has been developing microbial catheters. Then on Monday I had an interview with Professor Joe Shapter who told me that your team was leading this project. So I was wondering whether you would be able to provide me with some detailed information about this innovation?

In the article “Pinpointing Cancer Fight,” Liz Szabo states the uses of nanotechnology and how researchers are attempting to use this advancement to fight cancer. She defines that nanotechnology is a type of technology that creates devices on an atomic level; this equipment can allow people such as researchers to use its ability to detect cancerous cells as well as treat them. Szabo remains a neutral tone as she states that while some are against the idea of using nanotechnology since there are many risks, others are optimistic that it may lead to transformational results. She presents a list of some products developed through nanotechnology and explains its usage in addition to mentioning the failure of those nanotech products. Szabo provides

The main target of this research are two main groups, the spectators and the athletes. These are two important stakeholders being affected by decisions related to nanotechnology’s use in sports. The fans and spectators of sports were reached through an online survey. By posting the survey on multiple websites and forums I was able to reach out to different people in different countries and get a representative opinion about the given issue. The athletes on the other hand were approached through a focus group and one-on-one interviews. The opinion of these two groups is important to address the gap mentioned above since an agreement must be reached to what extent nanotechnology should be allowed or not. Moreover, this research will focus on Egyptian athletes and fans because Egypt is a developing country and one of the aims of this research is to try to see if developing countries will be able to benefit from nanotechnology in sports rather than developed countries.
...t biological science and technology can be developed safely and securely – so that they bring benefits, not danger” (Secretary-General, 2011).
It is clear that nanotechnology has the potential to revolutionize health care and even transport
Nanotechnology is defined as the science of design, synthesis and characterization of matter at the nanoscale, which mesures one billionth of the meter [1,2] On that scale, structures exhibit novel chemical, physical and biological properties and processes, which enables the creation of engineered nanomaterials (ENMs), with various characteristics and potential applications. [3] It’s not just that though. Nanotechnology shows the ability to eliminate the gaps among medicine, material engineering and science, computer technology and public policy, creating new clinical and medical approaches to better diagnose, treat and prevent any kind of illness. In fact, it is already moving from simple passive structures
Unit 3 Essay Assignment It is not immoral to develop GNR technologies even with the risks Anthony Beaster A sufficient number of the arguments against GNR (genetic engineering, nanotechnology, and robotics) technologies rest on unintended consequence theory, morality, and ethics. Ignoring the first for now, morality is the manifestation of the overall belief of what is good or right by the majority at some instance in time and ethics are the rules based upon the present morals.
...lready happening. It is too late to stop their development, we can only try to use them in a responsible and ethical way.
Nanotechnology is a part of a science and a technology abou the control of matter on the atomic and molecular scale. This means things that are about 100 nanometers or smaller. Nanotechnology includes making products that uses part of small, such as electronic devices, sensors, etc… Nanotechnology brings scientist and engineers together from many different subjects, such as applied physics, material science, interface science, device physics, chemistry Supramolecular chemistry and etc… When people talks about nanotechnology, they mean structures of the size is 100 nanometers or smaller. Nanotechnology is a unit that equals to 1 out of a billion. 1 nanometer (nm) is 1 out of a billion, which a hair of 1 out of ten thousand of a ultrafine world. For example, 3 or 4 atoms can fit in there. Furthermore, nanotechnology is small like nanometer making device controlling atoms and molecules by ultrafine technology. First human that made other scientist to lead to the world of nano was Richard Phillips Feynman who got Nobel Prize in Physics
The most exceptional trait about nanomedicine is its capability of eliminating cancers and tumors. Cancers and tumors have been a major problem for people worldwide, from families being torn apart, loved ones vanishing, and much more. Both being a complex matter to challenge as for many years it has been a problem and the closest thing that was thought to be the answer was chemotherapy. Many people have been wanting the actual cure and now we might have the answer. In the article “Nanomedicine”(2014), Guizhi Zhu, Lei Mei, and Weihong Tan establishes that:
Nanotechnology is science, technology and engineering that is conducted at the nanoscale. The nanoscale is about 1 to 100 nanometres.
Each of us lives with a modern paradox; how can we continue to enjoy the benefits of science and avoid the threat of its misuse or abuse to endanger life and nature? Responses to this paradox have been many, but seldom anything but emotional and impotent in making any useful changes. Among the strongest feelings brought forth by our increasing awareness of the negative side effects of technology has been the feeling of alienation that we in society have little or no control over the impacts of science and technology on those of us who are supposed to be their beneficiaries. We owe much to science. In fact, modern life would be unthinkable without it.
