The World of Mobile Phones

We live in an age where the lines between computer support and human support are blurring. In Nassau County computer repair means humans working on computers. In Suffolk County computer repair means humans working on computers. But in the halls of many major universities studies are underway that would flip the relationship. Computer repair would mean essential body immune response would be done by miniature computers. Nanotechnology has evolved and it is about to alter the world. An area most affected will be in the health industry.

Nanotechnology is the use of technology using very small things. A nanometer is a component of dimension. Nanotechnology useelements between 1 and 100 nanometers. If you took 800,000 nanometers and set them side by side it would be about the width of a hair. That’s small stuff. Being able to operate and manipulate elements at such a small level holds great potential benefit in the medical arena. Many institutions and researchers are engaged in exciting studies that could change the face of health care. Some advances are already occurring.

Presently a number of experiments are using nanotechnology in a variety of ways. One application is in how nanotechnology can help in diagnosing and treating cancer. A major downside to cancer treatments such as chemotherapy, is that it is a shotgun approach to treating the body. Healthy and unhealthy cells are attacked. With nanotechnology specific cells can be treated. There are studies that employee RNA strands that can locate and connect to cancer cells. Once attached these strands can release anti-cancer agents into the afflicted cells. Research has also considered the possibility of creating a color coding system using nanotechnology that would create protein indicators that would attach to cancer cells making them easier to trace. Another developing use nanotechnology in the fight against cancer is nanoshells. Nanoshells are made of tiny beads with various densities made of gold. These shells are attracted to cancer cells, surround them and then are heated with near infrared light which destroys the cancer cells, but spares the nearby healthy cells not surrounded by nanoshells.

Nanodevices would be small enough to enter a cell. They would be so small that they would be able to interact with proteins and DNA. They would be able to monitor the cell and detect disease using a minimal amount of valuable cell tissue. This means that diseases and change in cell tissue could be monitored and detected much earlier in the process. Because fighting cancer successfully depends on early detection, this would be a major advance in cancer fighting technology.

Nanotechnology is a rapidly developing area of science that combines many disciplines including; physics, chemistry, biology, engineering, and many other sciences including political and social science. With continual breakthroughs in all different fields, the world of Nanotechnology will be fully upon us.
