I had always been an athletic, healthy person, but in my late 30s my body started sending signals that something was wrong. I was tired all the time. I had no energy. I even started losing my hair.When I went to my doctor, the staff ran blood tests, but nothing ever pointed to a specific diagnosis. I lost weight. I couldn’t keep food down. I developed a butterfly-shaped rash on my face. I saw other doctors; they thought it was all in my head, and for a time, they didn’t believe I was physically sick.It was 1992 and the Internet was in its infancy, so I went to the library instead. I was very active in trying to figure out the problem, very vocal, and very angry to whatever was wrong that interfering with my life. I was 39 years old, I had a 3-year-old son, a husband, a home, and a full-time job as a nurse, and I had doctors telling me they didn’t know why I was ill.It took two years and four hospitalizations before my doctors figured out that I had lupus, a chronic autoimmune disease that causes inflammation, then swelling and pain, and eventually tissue damage throughout the body. I was relieved but also scared to finally know what was wrong.The story that I conveyed just now was a story of a SLE patient named Lenaki Alexander who had one of the most chronic diseases that had killed many lives over the centuries until now without them knowing why or how they got that deadly disease. Some suspects it could be certain genes make some people more likely to develop lupus or maybe an environment trigger such as specific virus or perhaps a certain lifestyle factor that could be the reasons, but yet to be discovered. However, SLE, an autoimmune disease in which your body’s immune system that attack your own cells and tissue is just one of over 7,000 diseases that yet we only have cures and treatments for 500 of them. So, in this day, I want to persuade each of you to support the idea of nanotechnology development by our scientists today. The nanotechnology or specifically nanorobots had profound the extension of health and longevity for the disease problem.The current status of disease and death is so staggering. In fact, diseases are the leading causes of death worldwide. A disease is a condition which threatens a human’s health that causing many problems. According to the World Health Organization (WHO), chronic diseases are the leading cause of death worldwide. Ischemic heart disease alone was responsible for about 9.43 million deaths in 2016. However, all cardiovascular diseases together cause over 17.8 million deaths annually worldwide.The group of major chronic diseases responsible for numerous deaths each year also includes all types of cancer, respiratory diseases and diabetes. In 2016, lung cancer alone caused over 1.7 million deaths, while liver cancer caused over 829 thousand deaths. Chronic diseases are especially widespread in developed high income countries. Here, Alzheimer’s disease and other forms of dementia have become more and more prevalent over the last decades. Communicable diseases are particularly prevalent in undeveloped, lower-income countries. Diseases like HIV/AIDS, malaria, tuberculosis, and all types of diarrheal conditions are much more prevalent than in undeveloped countries. For example, there were nearly 216 million reported cases of infections of malaria all over the world, with approximately 445 thousand deaths in 2016. Most of these cases and fatalities were reported in Africa.There is a solution. Or there may be in the future. Nanotechnology or nanorobots, is the key to the end of disease. Nanotechnology could be possible, practical and sensible way to treat the disease. Nanotechnology is a field of research and innovating concerned with building ‘things’, generally materials and devices on the scale of atoms and molecules.In the human body atoms come together to make many things, for example water, fats, hair, bones, and DNA. DNA and other molecules build cells and sometimes cells malfunction and cause diseases. Some of the diseases could be treated with by taking medicine or carrying out the surgery but most of them do not have the solution to cure them. So, this advance technology which nanorobots will be on the same size and scale as disease or pathogens since they able to work on a very molecular level. Nanorobots are implemented by using several components such as sensors, control, power and communications between organic and inorganic systems. These features could be used in surgery to detect the pathogens or diseases and then diagnosis and fix them. Besides that, nanorobots also can used for testing and monitoring the cells in our body such as noting down the record of the vital sign such as the temperature, pressure and immunity parameters continuously. The research by Dr. Samuel I. Stupp that designed molecules using naomaterials and had injected them into mice who were paralyzed due to spinal cord injury. After 6 weeks, the mice could able to walk properly. Research like this could potentially to evolve into the ultimate cure for very chronic diseases which include cardiovascular and neuron systems problem. This technology could be a hope to people that suffering from Alzheimers, Parkinson, brain injuries and tumors that have no cure until this day.Let’s see the other treatments such as chemotherapy which is the chemotherapy is the treatment that reduce the effect of tumors in patient’s body. As you know, chemotherapy releases toxic chemicals throughout the entire body rather than just the affected area, such as a tumor. This process destroys the cancer but also the immune system. Chemotherapy makes patients very sick, and there is risk of permanent damage or death from the treatment itself. Futhermore, the chemo drugs able to destroy the fast growing healthy cells throughout the body and potentially to lower our white blood cell production. This will lead to another exposure of infections that could affect your health. In fact, there is also a risk of the cancer returning as the doctor could be miss any cancer cells left in our body as the doctor could not able to detect them in a very molecular level. Thus, nanorobots are the solution that able to decrease the side effect of chemotherapy. The improvement of chemotherapy drug delivery by nanorobots to the target tumors were successfully without harming another vital organ in patient’s body. For example, a research that conducted at MIT where a nanotech gene therapy has successfully killed ovarian cancer and if successfully in human clinical trials, it could save many lives of 15000 women in a year.In conclusion, nanorobotics are found to exhibit a strong potential to diagnose and treat various medical conditions like cancer, heart attack, diabetes and other chronic diseases. While the severe side effects of the existing therapies are been considered, the nanorobots are found to be more innovative, supportive to the treatment and diagnosis of vital diseases. The nanorobots will allow us to achieving high efficiency against many diseases. Perhaps it could be one day, when one of our family members had been diagnosed to have a serious medical problem, this little thing could save his or her live. So, start by today, we have to support the nanotechnology development and we could save many lives in the future. Thank you.
