Nanotechnology studies the application of nano-sized materials for use across different scientific fields.

What are some benefits of nanotechnology?
A core characteristic of nanotechnology and nanoparticles are their small size. With an increased surface area material can increase their reactivity whilst using fewer materials. Nanotechnology can be used in many different areas, such as, medicine, agriculture and cosmetics.

Are there dangers or risks associated with Nanotechnology?
Organ dysfunction can occur in animals, nanoparticles can easily enter the bloodstream through inhalation or the skin due to their small size. (Raj et al., 2012)

Thesis: This essay will show that the benefits of nanotechnology outweigh its dangers, which can be controlled or lessened through research.

Body 1- Benefits in Medicine and Agriculture.

Radioactive gold nanotechnology has shown anti-tumor properties towards breast, lung, non-Hodgkin’s lymphoma, pancreatic and prostate tumors. (Katti, 2016)

Gold, silver and titanium dioxide nanoparticles can be utilised in agriculture. Titanium oxide nanomaterials improve crop yield and germination. Silver nanoparticles can add antifungal and antimicrobial coatings to plants including their seeds, and wood. (Sadeghi et al.,

    In order to ensure the safety of users of the Nachsicht device, it will go through a series of rigorous testing to assess its biocompatibility and ability to be sterilized. As the materials used in the Nachsicht, polymethyl-methacrylate (PMMA) and graphene, have been used in other biomedical applications, the host response to the device is highly predictable. Various options for sterilizing the device will be assessed. The tests will be performed in vitro and in vivo before proceeding to clinical trials in order to submit for and gain FDA approval. In order to assure the quality of a device intended for surgical implementation, it must be sterilized—that is, deficient of all living microorganisms—using the most effective methods.…

    Many environmental pollutants have been associated with human diseases. Our current knowledge of chemical induced adverse health effects is mainly limited to the toxicity of the individual chemicals. For the majority of chemicals, its individual toxicity is well documented, examples arsenic and skin, lung and bladder cancers; dioxin and chloracne; lead and neurotoxicity; benzo[a]pyrene and lung cancer. The scientific community increasingly recognizes the adverse effects associated with chemical mixtures are a serious concern. The task of generating data for all the possible combinations of mixtures would be difficult due to various factors, including an infinite number of combinations, difficulty in the selection of the dose range, application…

    The US also allows for a limited number of microorganisms, disinfectants, disinfectant byproducts, inorganic material, organic chemicals, inorganic chemicals, and even radionuclides which are byproducts from nuclear waste. Many of these contaminates have harmful side effects, which consumed in large quantities can lead to many health issues. Some of the contaminates are carcinogenic or a cancer-causing item, some lead to nervous system damage and harm a person’s ability to think, feel, and react. Various other contaminants cause more direct damage to certain organs like changing a person’s skin color or texture, causing thymus gland problems, liver and kidney problems, blood problems, cataracts, and even stomach and intestinal problems. Some may have an effect a person’s reproductive system or give a person anemia, a sickness that means a person has an iron deficiency.…

    The United States depends on a finite resource: fossil fuels. Easily accessible deposits of fossil fuels are dwindling, prompting stakeholders on both sides of the aisle to innovate and present options that either prolong the usage of our current energy sources, or harness renewable resources to reduce atmospheric greenhouse gases. Firmly backed by the President of the United States and top research institutions, solar energy, specifically converting light energy into liquid fuels, warrants discussion. However, solar breakthroughs generate questions, such as how a solar-powered country would operate while the sun is obscured or how cost-effective it would be to route solar derived power from ideal locations on the west coast to the less optimal…

    The essay, “It Always Costs” written by activist and scientist David Suzuki, argued for the importance of the negative outcomes of technology within our society. He further emphasized this idea by exploring the fact that although we rely and benefit from these technologies, everything comes at a price no matter how little or small it may seem. For example, malaria carrying mosquitoes, were being eliminated by a designed toxin (DDT) however, the genetics of the mosquitoes had mutated. As a result, the disease was difficult to erase and more toxins were used to improve the outbreak. The DDT affected the food chain and integrated into the egg shells of birds causing a high bird mortality rate.…

    Jacquelyn Tate Professor Ms. Melissa Erskine English 1301 4 April 2017 Genetic Engineering (Genetic Modification) is starting to gain ground in the world today and become an issue of major Controversy. Because of issues with genetic modification, things like the Human Genome Project has become an actual reality today that has been put into real life practice. Genetic Engineering (Genetic Modification ) is the altering or change by manipulating the genetic DNA structure of a single cell or of an organism. The manipulation of DNA signifies that scientists can target a specific gene in a person's body and change the DNA however, they want to. The technique of genetic modification is becoming so advanced that people today are already…

    They discovered a form of testing called in vitro which was based on human cells using robotic screening (Bin, A264). Through this method, human tissue is grown in test tubes which are then exposed to the new substances being tested (Cole). Test tube testing eliminates animals from being poisoned in order to differentiate toxic from non-toxic ingredients (Cole). This artificially grown tissue has proven to have more accurate results in testing irritation than animal testing does (Cole). After increased toxicology study, Walum stated, “as the discipline of cell toxicology developed over the years… the society reveal an increasing understanding and appreciation as true toxicological problems and challenges among participants” (Walum,…
