Medical Nanobots are tiny robots being used for medical purposes. With their implimentation, medical science would be revolutionized, and millions of people would be saved every day.
Imagine a robot so tiny, that it cannot even be seen by a microscope, yet it could fix your body in better ways than even the most expensive drugs in today’s market. Although this might sound like science fiction, we are very close to having such robots roaming in our bodies. In fact, ideas about such miniscule robots have been around for quite some time. In 1959, Dr. Richard Feynman, a noted scientist, imagined the use of such nanobots that would be only several atoms wide (Motavalli 25). These robots are being built today, and they are called nanobots. As robots continue to decrease in size, cell-sized nanobots that function at the molecular level will become reality. Many believe that within twenty years, these robots will be used to prevent and cure even the most bizarre and unknown diseases of today and the future.
One of the most deadly diseases, cancer kills thousands of people each year. The only treatments available right now are chemotherapy, radiation, and invasive surgery; all three spell disaster for the human body. Chemotherapy is made of highly toxic chemicals that kill not only cancer cells but healthy cells as well. Radiation creates similar results, with unwanted cells being killed along with good ones. Finally, invasive surgery can cause serious trauma that can kill at the operating table. However, the newly emerging nanobots seem to be perfect for the treatment for cancer. Because they are so small, they act on the body in the same way as bacteria, and they are capable of building with atoms and molecules themselves (Clare). “I believe that the first real application that will have a huge impact is in targeted cancer therapy, such a delivering therapeutic agents directly to the tumor through the vascular network,” says Sylvain Martel, director of the nanorobotics laboratory at Ecole Polytechnique de Montreal (Kroeker). This fact that nanobots will be able to give precise measurements of drugs to very specified areas in the body due to the fact that they will be able to reach every single part of the body is the main reason that nanobots will revolutionize cancer treatment. And because the drugs are administered to specific parts, they do not affect other tissues that would normally be affected by the drugs. In this way nanobots can save the patient’s body the trauma of today’s toxic and highly inefficient cancer treatment. In order to deliver such cancer treatment, Sylvain Martel and his team are designing a nanobot that can target regions that are inaccessible to traditional catheter techniques. They are using magnetic resonance imaging to give information to a control responsible for controlling the nanobot. Flagellated bacteria act as places to store therapeutic and sensing agents and thus serve a robotic arms that can perform different tasks (Kroeker). These nanobots, if successful, will open the doors to far less invasive techniques in cancer treatment that will drastically increase a patients chances to survive.
