The paper "Risks in Different Nanotech Applications" is an excellent example of a capstone project on technology. Nanotech has led to amazing innovations that have revolutionized many areas of human life due to its many applications. The uses include medical uses, industrial processes, materials such as clothes, electronics, molecular manufacturing, sustainable energy applications, environmental applications, robotics, and many others. The use of nanotech has had numerous benefits. This report starts by exploring the benefits of nanotechnology in medicine. Every good innovation has its drawback and thus the application of nanotechnology is not unique since it has various drawbacks the make its application risk to human and environmental health.
In this regard, the report will explore the various risks associated with the application of nanotechnology in various application platforms. The report will also provide the reasons why it is important to understand the risks associated with the application of nanotech. On a positive note, the report will discuss these risks as well as their possible solutions. It will also provide the social and political impacts of the risks and solutions. Benefits Used in medical Diagnostics: Nanotech is emerging as a useful medical diagnostic tool.
It is being developed as a method of detecting cancer cells in the bloodstream using nanoparticles called nanoflares. These nanoflares generate light when the genetic target in question is detected. In the meantime, researchers are developing a certain nanoparticle which will make detection of cancer tumors easy and as early as possible (Shrivastava & Dash, 2009, p. 2). There is also a development of a method of detecting brain cancer using magnetic nanoparticles together with nuclear magnetic resonance (NMR) technology. They have also included Carbon nanotubes and gold nanoparticles in the detection of proteins that indicate the presence of oral cancer.
Research has proven this test to be very accurate and first enough to produce results in less than an hour. Silver nanorod has been adopted for use in a diagnostic system that uses blood samples and effectively separates bacteria, and viruses, among other microscopic components. In a laboratory, sample nanoparticles can facilitate disease early detection, since they attach to proteins and other molecules (Patil, Mehta & Guvva, 2008).
The flu virus can be detected very first by gold nanoparticles. Early detection approaches for illness need nanoparticles that develop clumps. Quantum Dots in the future may be used for locating cancer tumors and performing diagnostic tests in samples. Since there are concerns due to the toxicity of using quantum, there are restrictions on usage on human patients. Either way, these lead to the development and use of quantum dots which are composed of silicon hence less toxic. A combination of Gold nanoparticles with fluorescent protein is used in systems diagnosis to determine the type of cancer present. In image diagnostic, using Nano-roughed glass plates researchers have found out that cancer cells in the blood can be captured and this will enable them to comprehend the way it spreads from tumors.
To improve MRI imaging for cancerous tumors, iron oxide nanoparticles are frequently employed due to their effectiveness. Nanotechnology is used as a form of therapy (nanomedicine) Nanotech can be used in repairing cells. Miniscule devices and robots are constructed and enter the body to facilitate various operations (Patil, Mehta & Guvva, 2008).
This is possible because they can distinguish molecules of particular body cells from another using nanotechnology. Damaged heart tissues can be repaired using nanobots. It can also be used in the treatment of other heart diseases like unclogging cholesterol-filled arteries. It has also enabled a first bone repair technique by the use of polymer scaffolds with stem cells.
