1.) What is the technology?
Nanotechnology is the study and application of extremely small things and can be used in other fields of science, such as engineering, physics and material science. Nanotechnology is science, technology and engineering all studied at the nanoscale, which is less than 100 nanometers. Originally nanotechnology referred to the capability of building objects from the bottom up, using the tools and techniques developed today to make completed high end performance products. The manipulation of items within the body at the atomic and molecular level is rapidly expanding in the area of research with huge potential in the healthcare sector. “In medicine, it promises to transform drug delivery, gene therapy, diagnostics, and many areas of research, development and clinical application.” (http://www.medicalnewstoday.com/articles/244972.php)
2.) What purpose does this technology serve?
DNA-based nanobots have been generated to target cancer cells. For instance, researchers have reported how they made a nanorobot out of DNA to transport a molecular shipment. The nanobot can carry molecules throughout the body directing the cells to behave in a particular way. Researchers have successfully demonstrated how it delivered molecules that trigger cell suicide in leukemia and lymphoma cells. Another form of nontechnology scientists have created is nanostars, which are simple, specialized, star-shaped nanoparticles that allow the delivery of drugs directly into the nuclei of cancer cells. Nanostars act like tiny hitchhikers, after being attracted to an over-expressed protein on the surface of human cervical and ovarian cancer cells, are deposited into the nuclei of those cells. Researchers concluded that giving their nanob...

... The third generation will feature nanosystems with thousands of interacting components. Finally, the first integrated nanosystems, functioning with hierarchical systems within systems, are expected to be developed. Nanotechnology can also be known as general-purpose technology. In its advanced form it will have substantial impact on a numerous amounts of industries within society. It will offer better built, longer lasting, cleaner, safer, more smart merchandise for communications, medicine and for industry in general. “Imagine a medical device that travels through the human body to seek out and destroy small clusters of cancerous cells before they can spread. Or a box no larger than a sugar cube that contains the entire contents of the Library of Congress. Or materials much lighter than steel that possess ten times as much strength.” (http://crnano.org/whatis.htm)
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?
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
Cancer has been an active concern in our society for the past couple decades, since we truly discovered the nature of cancer and the potency it brings along with it. However, it was not until the mid-20th century that scientists were beginning to truly understand the origin of cancer. Scientists dating back all the way to the Renaissance, when they first began performing autopsies to learn more about the human body and form, noticed abnormalities but it never clicked that it was something much worse than it seemed. Research has continued since then, and it has continued to thrive even to this day. When James Watson and Francis Crick discovered DNA and it’s chemical structure in 1962, it opened up doors that even they could not expect. With the understanding of DNA and how it affected the way we look at life, came the beginning of the understanding of mutated DNA (which is a cause of the growth of cancerous cells). In this past century, researching scientists discovered that cancer is linked with the DNA that resides in a cell’s nucleus. By ways of damage to the cells via chemicals or radiation, or even introduction of a new DNA, the cancerous cells begin to form and duplicate. We are learning more and more about cancer and how to fight it, but we still have much more to learn.
It is clear that nanotechnology has the potential to revolutionize health care and even transport
Gene therapy is a relatively new concept owing mainly to our current knowledge of the human body and the relatively modern understanding of genetic coding and process. We now are able to better identify and understand the genetic causes of human ailments, and are just beginning to understand how to fix, replace, or eradicate the chromosomal basis for these issues; this is the concept of gene therapy. However logistically dealing with the small structure of genes, chromosomes, and DNA is not as easy as repairing a cracked wall or damaged water pipe, we are dealing with complex and microscopic materials that ordinary tools cannot deal with. Manufacturing such tools to deliver corrective DNA into affected cells within the body is just one of the obstacles that scientists and researchers are facing.
Nanotechnology is defined as the science of design, synthesis and characterization of matter at the nanoscale, which mesures one billionth of the meter [1,2] On that scale, structures exhibit novel chemical, physical and biological properties and processes, which enables the creation of engineered nanomaterials (ENMs), with various characteristics and potential applications. [3] It’s not just that though. Nanotechnology shows the ability to eliminate the gaps among medicine, material engineering and science, computer technology and public policy, creating new clinical and medical approaches to better diagnose, treat and prevent any kind of illness. In fact, it is already moving from simple passive structures
Almost everyone is touched by cancer in some way and the number of people living with and beyond cancer grows greater every year. Globally 14 million people are diagnosed with cancer each year and 8 million people will die from it annually. Half of all men and one-third of all women will develop cancer during their lifetime. (13) There are many treatments for cancer, mainly: surgery, radiation and chemotherapy. These traditional treatments have many negative side effects. Therefore, increasingly, other treatments, such as hormonal therapy and targeted therapy are being used for certain cancers. Nanotechnology is a form of targeted therapy that destroys cancer tumors with minimal damage to healthy tissues and organs. Scientists are already using nanotechnology in early detection of elimination of cancer cells before they form tumors. But the real game changer will be when nanotechnology targets cancer tumors in treatment (11,13).
Over the years, our scientists and doctors have made a substantial amount of progress. As we prepare for the future, we must wonder if we will have enough doctors, nurses, and researchers who specialize in cancer. Even though we know a great deal about Biology, we will always continue to uncover new knowledge in the future. Hopefully our knowledge of Biology will help scientists and researchers to develop new cancer screening methods and cancer drugs that will be effective against cancer. An ideal solution would to be able to figure out how to destroy cancerous cells without them returning or spreading to other areas of the body, and without killing off healthy cells. Our knowledge of cancer is still expanding, and will continue to over the years to
An ordinary human body contains approximately one trillion cells and precisely 46 chromosomes in each cell. However, the human body can be altered by a genetic mutation. Over the course of history, genetic mutations have had a large impact on the human race. They have brought harm to numerous amounts of people. Cancer, in particular, is one of the most lethal diseases. Cancer begins when a portion of DNA inside a chromosome is damaged, causing a cell to mutate. Then, the mutated cell reproduces multiple times and creates a tumor. Afterwards, cancer cells break off of the tumor, enter the bloodstream, and disperse throughout the body. If the cells break off, the tumor is considered malignant - this type of cancer is very difficult to cure. Many patients today stay optimistic for a medication to heal cancer. It is imperative to address a few of the causes and effects of cancer in order to gain a general knowledge of genetic mutations.
First things first, what exactly are nanotechnology and biotechnology? There has been some less than mild discussion of late about what constitutes legitimate nanotechnology, and suffice it to say that it doesn’t include things like laundry detergents, chemical additives, makeup micro-beads or anything of the like that may be claimed by some companies that are looking for an advantage over their competitors. Also, neither of these growing scientific disciplines includes any of the many terrifying, often alien technologies that swarm and smother, seek and destroy, or otherwise attempt to eradicate the human race from the face of the earth, ad nauseam. Here is a concise definition from The American Heritage Science Dictionary: “Nanotechnology is the science and technology of precisely manipulating the structure of matter at the molecular level. The term nanotechnology embraces many different fields and specialties, including engineering, chemistry, electronics, and medicine, among others, but all are concerned with bringing existing te...
“Since 1990, over 6 million Americans have died of cancer, more than the combined casualties from the Civil war, WWII, and the Vietnam and Korean conflicts combined” (Faguet, p. 5). According to American Cancer Society projections, there were 1,529,560 new cases of cancer in 2010. Cancer is becoming more and more common around the world. New cancers are constantly being discovered. Researchers are finding new ways to detect cancer and treat it so that the fatality rate does not rise. However, there are some cancers that researchers have not yet discovered a cure for. It is very important for Cancer Research to continue so that one day these cancers will no longer be a treat.
Cancer is the uncontrolled growth of abnormal cells in the body. Tumors are then created and interfering with the digestive, nervous and circulatory systems. It is one of the most leading causes of death, reaching at about 8.2 million deaths in 2012. It is expected that cancer will rise from 14 million to 22 million within the next 2 decades. With over 100 cancer research centers in the United States studying how to treat this disease, people need to understand the importance of donating also with the awareness of signs and symptoms in the early stages. But, what are we doing about it? Do we have the technology to finally be able to put this deadly disease to an end?
Regenerative medicine targets the conservation and development of organ function. The modification of tissues is obtained by linking living cells with materials that work as scaffolds to support cell generation. Nanotechnology is the means that feeds the material structure that simulate biological ones and additionally provide a direct delivery system. The functionality of nanotechnology for regenerative medicine is primarily due to its small unit size according to the International System of Units, one nanometer is one-billionth of a meter. The unit size allows for the technological apparatus to navigate the bloodstream and target and fix damage cells in tissues.
Nanotechnology is science, technology and engineering that is conducted at the nanoscale. The nanoscale is about 1 to 100 nanometres.
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.
