Recommended: Uses of nanotechnology

Nanoparticles are so small in size that they can enter cells and organelles to interact with DNA, proteins, enzymes while circulating throughout the body. Therefore, nanotechnology is used in detecting disease in a very small volume of cells or tissue [1].As mention above; commonly used nanoparticles are such as, gold nanoparticle, silver nanoparticle, quantum dots and magnetic nanoparticle. Gold nanoparticles have unique stability against oxidation which makes it useful in diagnostic. Its benefits such as much reduced or no toxicity, much better contrast agents for imaging, and surfaced-enhanced and distance- and refractive index dependent spectroscopic properties compare to other nanoparticles, makes it the best choice of selection for enabling early diseases detection [2,3].

The use of nanoparticles for the detection of experts is a topic of interest that is being passively discovered for many applications [4]. Firstly, the capability of a nanoparticle to identify a tissue of interest is perhaps the most potential abilities in nanotechnology. Nanoparticles are used in selectiv...

    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?

  • Rhetorical Analysis Of Pinpointing Cancer Fight By Liz Szabo

    379 Words  | 1 Pages

    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

    They have a larger surface area in proportion to their volume. This enables them to interact with different types of biological systems and provides a wide variety of possibilities (Nuruzatulifah, Nizam, & Ain, 2015). The nanoparticles can be seen by transmission electron microscopy (TEM). When there is one nanoparticle, it is called a primary particle. When there is more than one, it is called a secondary particle. In order to measure these particles, they need to be suspended in a solution (Pruneanu, Coros & Pogacean, 2015). Dyed nanoparticles or internally fluorescent nanoparticles barely interact with cellular proteins which is what the study requires. They are also quite easy to manipulate. They can be easily internalized into cells and can be programmed to go to specific sites (Wolbeis,

    Nanomedicine is offering incredible and innovative therapies like cancer nanomedicine, nanosurgery, and tissue engineering. In cancer nanomedicine, they use “targeted drug delivery” to target the tumor itself and avoid harming the normal, healthy cells (Berger, 2017). This in return, offers a more effective treatment with better outcomes and less side effects. In cancer nanomedicine, nanoparticles are used as tumor destroying mediators that use high temperatures to destroy them. These nanoparticles have to be injected into the tumor, then they have to be activated to produce this heat and then they are destroyed via a magnetic field, X-rays, or light (Berger,

    ...nessing “the power of nanotechnology” to radically change the way we diagnose, treat, and prevent cancer.” The most likely method implemented will by the use of nanovectors for targeted delivery of anticancer drugs, and then heating nanoparticles that are attached to cancer cells so that the cancer cells explode. (5, 9) There are still many obstacles that must be overcome before this is a reality: from the ethical concern by some that nanobots will take control of the body to the more practical problem that this method of treatment will be very expensive and funding will be an issue. (6) But with millions of people suffering from some form of cancer, scientists are searching for cures and treatments and nanotechnology offers the greatest promise. One day, cancer may be completely curable thanks to nanotechnology which is something everyone would benefit from.

    Gold has long been used within the human body for many surgical treatments. Due to the chemical nature of gold, it does not readily react with other compounds inside the human body and is not damaging to the surrounding cells. Furthermore, it will not corrode or break down because it does not interact with oxygen. This allows scientists to implant gold nanoparticles within cancerous cells in preparation for treatment. After injecting the nanoparticles, which are smaller than a red blood cell, they begin to accumulate within the rapidly-growing cancer cell, where they wait until further treatment.

The book Nanotechnology Demystified explains “These nanowire detectors can also tell the difference between viruses with great accuracy. If single wires were combined into an array, it is possible that complex arrays could be designed that are able to sense thousands of different viruses.” (Williams, and Adams, 96) These wires are made of various materials such as lead.

    Nanotechnology, shortened to "nanotech", is the study of the control of matter on an atomic and molecular scale. Nano science and nanotechnology are recent, revolutionary development in Science and Engineering that are evolving at a very fast pace.[1,2] It is driven by the desire to fabricate materials with novel and improved properties that is likely to impact virtually all areas of the physical and chemical sciences, biological sciences and health sciences. The word ‘nano’ derives from the Greek word ‘nanos’, which means dwarf or extremely small and mathematically, a nanometer is a billionth of a meter or 10-9 m. Particles whose sizes fall in the size range of 1-100 nm is called a nano particles, whether it is dispersed in gaseous, liquid or solid medium. Generally nanotechnology deals with structures of the size 100 nanometers or smaller, and involves developing materials or devices within that size. Nanotechnology is very diverse, ranging from extensions of conventional device physics, to completely new approaches based upon molecular self-assembly, to developing new materials wi...

    Science in the ancient world was a complex concept. There was a varied, and at times mixed, emphasis on the mythical, or theoretical, and practical components of science, depending upon where the “science” was practised. Theoretical science, as described by Peter Dear, is abstracted practice, while practical science is applied theory. Whilst, the ancient Greeks generally placed more emphasis on theory, the ancient Egyptians generally took knowledge and applied it in a practical manner.
