Risks in Different Nanotech Applications - Literature review Example

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 that will make the 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.
