Nanotechnology : Science, Engineering, And Medicine

Have you ever drove home from work, having a feeling you were forgetting to do something important? It’s 7 o’clock in the evening, you just realized that you were supposed to pay a bill before the bank closed. The money is there in the account but, how is the bank supposed to receive it? Well, luckily you pull out an iphone 6 to transfer the money into the account to pay the bill by using e-banking. Simple as that, you go home with a clear conscience knowing only that your bill is paid. Of course, people only care for the end results of a situation, but it’s sometimes good to consider what goes on in the transition. Crucial data such as financial record and pin number need to be under tight security. Only highly advanced technology that was

Several findings are made based on the results: UV radiation can cause cell death by inducing genetic mutation, which agree with Diepegen et al. (2012)’s finding regarding UV radiation’s destructive effect at a cellular level. Photoprotective agents can effectively prevent and reduce UV radiation induced damage to cells. Similar findings were made by Quatrano and Dinulos (2013), who indicated that sunscreen contains active ingredient that absorbs UV radiation ranging between 290-400 nm. This experiment proves that photoprotective agents with higher SPF values are more effective in absorbing UV radiation. Indicated by Green et al. (2011), they suggested that regular application of high SPF sunscreen will prevent melanoma.

In the United States, more cases of skin cancer have been diagnosed than any other type. It is estimated that about 2 million of these cases arise every year, and can be prevented significantly from utilizing sun protection.

For this year’s science project, I would like to test the effects of both mineral and commercial sunscreens on human skin and coral reefs. In current news, the island chain and United States’ state, Hawaii is planning on banning common sunscreens for the detrimental effects on the coral reefs. I would like to test the sunscreens for the detrimental effects on human skin as well to answer the common question, “Why should I care?” With this project, I will be able to educate the public on not only the effects of chemicals on marine life, but also on humans as well. Also, determine if there is a way not to wear sunscreen at all and still be protected from the sun’s UV rays.

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.

Through writing this research paper, my comprehensive knowledge about skin cancer has largely increased. In researching, I discovered the absolute importance of wearing sunscreen and covering the skin whenever possible - while I have always been aware that UV radiation is not healthy for the skin in large amounts, I had forgotten the importance of covering up. Furthermore, I learned more about each individual type of skin cancer, and was particularly shocked that all three types can be easily treated when detected early. There are few cancers that can be treated and cured effectively, even in early stages. As the most common form of cancer in the United States, it is important to be informed about skin cancer and to know how one can prevent it and how one can detect it in its early

It’s that time of the year that we all look forward to. The sun shimmers in the azure sky and provides the perfect environment for outdoor enjoyment. From lounging on the beach to sauntering in the park, we are all eager to make the most of the beautiful weather. There however exists one daunting reality related to exposure to the sun; the threat of Skin Cancer.

Ultraviolet (UV) radiation associated with skin cancer is one of the most common cancers. If the skin is exposed to the sun, some humans would have a higher risk of skin cancer. Sunscreen is a source that protects the skin, which is highly recommended to be used if your skin is sensitive to the sunlight. This theory will show how students who attended Human Biology Lab class approach on how certain level of SPF in sunscreen can protect the skin. There were significant differences found in the different brands, but not a major significant in some. In the end, the results showed that the UV intensity data were accurate.

Many skin cancers can be prevented by avoiding triggers that cause tumors to develop. Prevention strategies include protection from the sun by the use of sunscreens, protective clothing, and avoidance of the sun during the peak hours of 9 a.m. to 3 p.m. Parents should ensure children are protected from the sun. Do not use tanning beds, which are a major cause of excess ultraviolet light exposure and a significant risk factor for skin cancer. The American Academy of Dermatology (AAD) has noted a dramatic rise in the numbers and cost of skin cancer. Furthermore, there has been an increase in the total number of skin cancers and that new breakthrough treatments for melanoma, although expensive, comprise only a small portion of the total cost of skin cancer treatment. Most skin cancers are treated cost efficiently by dermatologists in an office

But today, we propose for Nanomedical robots, since they will have no difficulty in identifying the target site cells even at the very early stages which cannot be done in the traditional treatment and will ultimately be able to track

Over the years of human existence, it was proven that superior technology, especially within the military, dictated the strength of a civilization. Modern warfare was again advanced with technology from the industrial age of the Great War. Society, again, has reached a new age of warfare with nanotechnology. Nanotechnology and nanoscience is the manipulation of matter at the atomic and subatomic level. Many uses are brought with nanotechnology, such through medicine and manufacturing because of the ability to alter matter. This ability has also opened the gate toward military technology. Research has begun to create an advanced “super soldier”: A soldier who has been enhanced through technology, making them superior on the battlefield. Nanotechnology has also help to enhance reconnaissance and medical-aid on the battlefield. Even though advancements within military technology could help a nation gain an advantage over another with fewer casualties and faster victories, ethics on the use of these technologies have to be questioned; Is security more important than privacy? What happens if the enemies obtain these weapons? Or, is it safe for humans to use? Nanotechnology brings a

In summer, 70% of women use a sunscreen under their makeup. Yet, these products involve Retinyl Palmitate which supports the growth of cancerous skin tumors and lesions. The majority of sunscreens are harmful, do not protect the skin from cancer, and are loaded with

The idea of placing a very small controllable object into the human body in order to accomplish a medical feat, believe it or not, came from a science fiction film! In 1966, a movie by the name of Fantastic Voyage was produced and explored the subject. In this movie, a spy with critical information was nearly assassinated and left comatose with a potentially fatal clot in his brain. To save his life and to retrieve the top secret information, a submarine was shrunk to microbe size and injected into his body with a team of surgeons onboard. The team navigated to his brain to mechanically destroy the clot and save the spy along with his secret information.
