We live in an age where the lines between computer support and human support are changing. In Nassau County computer repair means people fixing computers. In Suffolk County computer repair means people fixing computers. But in the labs of esteemed universities studies are underway that would turn that notion on its head. Computer repair would mean essential body immune response would be carried out by miniature computers. Nanotechnology has evolved and it is about to alter the world. An area most affected will be in medical technology.
Nanotechnology is the use of technology using very small things. A nanometer is a unit of dimension. Nanotechnology useunits between 1 and 100 nanometers. If you took 800,000 nanometers and set them next to each other it would be about the width of a hair. That’s small stuff. Being able to operate and manipulate elements on such a tiny scale holds great potential benefit in the medical arena. A great number of research institutions are engaged in exciting studies that could change the face of health care. Some advances are already happening.
Currently there are many different studies using nanotechnology in a various methods. One area of interest 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. Normal and cancer cells are attacked. With nanotechnology only cancer cells can be targeted. There are theories and trials that employee RNA strands that can find and attach to cancer cells. These strands, when connected can deposit cancer fighting drugs 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 find and link to cancer cells for easy identification. An additional application nanotechnology in the treatment of cancer is nanoshells. Nanoshells are made of minute 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 tiny enough to operate inside a cell. They would be so small that they would be able to interact with proteins and DNA. Nanodevices could monitor the cell and detect disease using a smaller quantity of cell tissue. This means that diseases and change in cell tissue could be monitored and detected sooner. Since success in fighting cancer often depends on early detection, nanodevices would start a revolution in cancer fighting technologies.
Nanotechnology is a rapidly developing area of science that utilizes a wide array of disciplines including; physics, chemistry, biology, engineering, and many other sciences including political and social science. With ongoing discoveries in all different fields, the advent of Nanotechnology will be fully upon us.
