Essay on Use of Nanotechnology in Medecine

Over the years, surgery has made tremendous progress while changing human perspective; viewed as “no more science than butchery” a couple of centuries ago to now considered to be a solution for many health care problems, such as cancer, heart disease and kidney failure. Nevertheless, surgery has not been perfected to a level that provides great results every time it is performed on patients. For example, surgery done on cancer patients to remove tumors has a forty-five percent success rate (Cancer Research UK, 2013). However, in order to be successful, the surgical procedure has to be performed very precisely. And incomplete removal of tumors can decrease the patient’s survival rate and potential of future build up.

They are different, because you can see so much more when you look through a microscope. For instance, you can see a strand of hair through a camera, at a tenth of a millimeter, but not a cell, at 100th of a millimeter.

It is agreed upon that nanotechnology, like most emerging technologies, requires proper, consistent, and coherent governance, however legal and regulatory questions associated with the technology remain, mostly due to uncertainty and the public’s lack of trust in what may be considered controversial applications and the transparency of the legislative and regulatory decisions. Considering the vague definition of nanotechnology the Foresight Institute encourages self-regulation within the scientific community in order to avoid legislators poorly informed decisions. However, some commentators believe that the public must be informed of the possible risks and regulations and policies must protect the best

"By the Light of the Moon" by Dean Koontz weaves the biological concept of nanotechnology in humans into a mysterious story plot that discuses the morality of it and effects of its possible advancement. Koontz theorizes the future scientific concepts of advancement in DNA manipulation, time travel, metaphysical abilities - such as teleportation, and clairsentience. A psychopathic doctor injects an unknown serum into unwillingly people without definite knowledge of side effects, demonstrating an example of "bad science". The doctor acted on selfish intent to disclose evidence of his illegal drug without actually having his creation destroyed. "I'm injecting you with my life's work" (page 18) "there's no way out for me, but {no way} I'll let

The Portuguese Neurologist Antonio Egas Moniz is said to be credited with inventing the Lobotomy in 1935, for which he shared the Nobel Prize for Physiology or Medicine in 1949. (Official website of the Nobel Prize, http://www.nobelprize.org/) Before the procedure was tested on humans, it was actually tested on chimpanzees by a Yale Neuroscientist John Fulton and his colleague Carlyle Jacobsen in 1935. Because of certain behavioral and personality issues, the procedure was sought to adjust the way illnesses were developed, and to eliminate them. The procedure was done by cutting holes in

Hugh Savagè has liver cancer. Chemotherapy failed, surgery failed. In a last ditch attempt to save his own life, Hugh signs up for a miracle trial using nanotechnology. In this trial, the widely-used chemotherapy drug Epirubicin was attached to nanodiamonds (carbon structures with a diameter of about five nanometres) to cultivate a nanodiamond-Epirubicin drug delivery complex (EPND). Researchers have found that while both the usual Epirubicin and EPND are capable of killing normal cancer cells, only EPND is capable of killing chemo resistant cancer stem cells and preventing secondary tumour formation in xenograft models of liver cancer.

In a move to transform the nation's medical research capabilities and speed the movement of research discoveries from the bench to the bedside, the National Institutes of Health (NIH) has laid out a series of far-reaching initiatives known

Nanobots are invented to solve problems concerning cancer. Uncontrolled mitosis leads to cancer which have higher tendency to happen when mechanism that controls the cell is distrupted. In 2012, according to the World Health Organization, cancer is one of the leading cause of fatal. In Canada, approximately 30% of deaths are caused by cancer and abouy 191,300 new cases of cancer are expected in the year 2014. Annually, 14.1 milllon of new cases were reported while globally, there were 8.2 billion of deaths. Cancer cells need to compete with normal cells to obtain sufficient nutrient and energy for growth. Cancer cells divide out of control and are able to able to spread to other cell, tissue and organ which will result in malfunction and death.

There might actually be a tiny--or nano, rather--electronic device that can be injected directly into your brain or other parts of the body.

Throughout our history, scientists continue to experiment and make discoveries that expand our knowledge of the world and the full potential of the matter around us. As the medical research of scientists improves, new treatments are found that enable people to have a longer lifespan and live healthier. Medical researchers continue to discover new medicines that help people overcome fatal diseases and allow them to achieve a more sustainable life. As scientists research the potential of treatment for diseases, there is a promising future in stem cells that offer a possible treatment for a wide variety of diseases. Scientists discover the capabilities of stem cells through their ability to repair, their opportunity of treatment, and their

Over the course of many centuries, medical technology has developed to a great extent. Studies show that recent equipment has evolved more in the last ten to twenty years than in the past thousand years. Before human time, people learned to treat themselves by just using natural substances. Now-a-days, our hi-tech systems in the medical field have been created for the most effective tools for a high level of patient care. While they advance the tools, it will then allow for quicker diagnosis, less pain, and fewer costs, which in the end will help save more lives. Some people are accepting that modern technology can buy them more time to live while others might find it quite alarming because they fear

Nanotechnology is the development of atoms in a certain object. Nanotechnology has become very popular in the past few years. It is a way to rebuild the systems of life. To make systems move faster than ever before. Nanometer is about 10 times the size of an atom. Each of these has a huge effect on a system. Still there are questions out there that keep people wondering how important nanotechnology is to us. Many wonder how will it affect them and if we should continue this research. I myself wondered about nanotechnology. After researching this topic I have learned new and interesting facts to help me understand the entire concept.

Nanotechnology is the gateway to near limitless possibilities for the human race. It opens the window to a new realm we previously have never experienced-- Nanotechnology is a branch of engineering that deals with the manipulation of atoms at the molecular level. The Institute of Nanotechnology in the U.K. expresses it as "science and technology where dimensions and tolerances in the range of 0.1 nanometer (nm) to 100 nm play a critical role”. Once automated, the nanoparticles will infiltrate every aspect of our lives- from medical, engineering, biomaterials energy production, to name a few. Practically everything we use today could be replaced by nanomaterial in some way, and it even has the capability to create new materials.

Most microscopes, including those in schools and laboratories today, are optical microscopes. They use glass lenses to enlarge, or magnify, an image. An optical microscope cannot produce an image of an object smaller than the length of the light wave in use. To see anything smaller than 2,000 angstroms (about 1/250,000 of an inch) a wave of shorter length would
