Nanotechnology and its importance in cancer treatment
Nanoscience:
Nano refers to 10-9 power or one billionth. Nanoscience is ths study of atoms, molecules and objects whose size is on the nanometer scale (1-100nm)
Nanoscience is the study of metal nanoparticles (Banerjee et al, pp. 42) ,and these particles are widely distributed in nature. These particles may be form when volcanic eruptions spew out materials from below the earth surface or when tidal waves erode a coast or bank. The notorious eruptions of Eyjafjallajokull spread in the atmosphere nanoparticles of size range 100-400nm (Harrison et al, 2010).
Nanotechnology:
Nanotechnology is the engineering multifunctional devices within the molecules.In recent years, nanotechnology has been

Applications of nanotechnology in biotechnology are following
More predictable drug toxicity based on surface level characteristics such as charge or particles positioning of nanoscale molecule material
More efficient drug delivery mechanism through nanoscale manipulation
Better controlled drug delivery
Other applications include better product development for sunscreen, cosmatics, paint, and disinfectant manufacture.(Barkeley Law Journal pp.321)
Nanotechnology in medicine:
Nanotechnology in medicine involves applications of nanoparticles currently under development, as well as longer range research that involves the use of manufactured nano-robots to make repairs at the cellular level (sometimes referred to as nanomedicine).
One application of nanotechnology in medicine currently being developed involves employing nanoparticles to deliver drugs, heat, light or other substances to specific types of cells (such as cancer cells). Particles are engineered so that they are attracted to diseased cells, which allows direct treatment of those cells. This technique reduces damage to healthy cells in the body and allows for earlier detection of
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?

Ultrafine particles can be defined as nano-sized particles which is less than 100nm. However, it is not manufactured purposely and not inevitably exist in a constant size. It is also known to be appeared by friction or combustion process, natural process in the air or water. (United States Environmental Protection Agency, 2013). Besides that, ultrafine particles can be described as the smallest fraction in a scale of airborne particles with diameters ranging from a few nanometers to several nanometers. Even they are small particles in size, they are dominant contributors to particle number even it is capable to contribute little to the mass of particulate matter in ambient air. (Health Effects Institute, 2013). They are also represent about 80% of particles in terms of number concentration in an urban environment (Morawska et al., 1998). There are variety of sources of ultrafine particles. According to Cess et al (2000), the major sources of ultrafine particles is from combustion process which is comprised of vehicle emission, stationary sources fuel combustion, non-highway mobile sources such as diesel off-road vehicles, and other mixed emission from open
Nanotechnology is special because it can ensure that the other healthy body cells won't be affected by the
For instance, Primark 's products offer customers clothing as a base product, of witch actual benefits are being to be cheap and trendy, and they may have some return policy as augmented benefit in case of defects. Each product may be realised following a new product development process to improve its success rate (Harris and Schaefer, 2015, p.43-47).
...signal to each other to change the response. This model provides a more accurate representation of how the human body would respond to a toxic nanoparticle since it is more complex and allows for cellular interactions and robust responses. This model is also useful if scientists are interested in studying animal responses to the nanoparticle, since the measured results are more accurate compared to monoculture models.
Medical technology is advancing faster today than ever before allowing for easier, faster, simpler and advances in medical devices, procedures and diagnosis’. Medical devices also keep getting smaller; very, very small – the size of a nanometre. Nanotechnology is technology that controls matter at a molecular level. Nano means one billionth of a metre which is the range of an atom. (Appendix 1, Figure 1)
...on products, ranging from refrigerators to vacuum cleaners to chain saws, in more than 150 countries.

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 production of synthetic detergents are an example of a standard chemical approach. If a useful substance has some undesirable properties an attempt is made to make a near copy synthetically which will perform better.
We also have learned that although nanotechnology has been around for a decade, there is still a long way to go to perfect this technology. Biomedical scientists and Nano-engineers have to work together so that all the nanobot promises are met safely and effectively. Our group is excited to see this technology continue to evolve. We are even more excited to finally see nanotechnology being used in the human body.
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 includes nanorobots which are so small that they can be injected into the human bloodstream after which the nanorobots can do investigations or repair at cellular level. Nanorobots could optimize the delivery of pharmaceutical products, these means that medicines which are targeted on a specific type of cells can be delivered to only those cells by the nanorobots. The robots can attach to the cells after which they can inject the drug into the target cells. This could be a great breakthrough for cancer treatments such as chemotherapy because there is a minimal chance of injecting healthy cells with the drug and therefor negative side effects can be avoided.
Nanotechnology is science, technology and engineering that is conducted at the nanoscale. The nanoscale is about 1 to 100 nanometres.
