In recent years, researchers around the world have shown increasing interest in the field of nanoscience. Nanotechnology is the research and development of materials, systems and devices with properties different from those found at the scale of molecules and viruses (Patil et al). A branch of nanotechnology, called nanomedicine, holds great promise for future medical advances in the prevention, diagnosis and treatment of diseases (Patil et al). Nanomedicine is a science and technology that involves preventing traumatic injuries, relieving pain and maintaining human health (Patil et al). Using nanomedicine, it will be possible to extend the lifespan of a human being by quickly repairing various life-threatening physical injuries. Medical robots, or nanobots, will be able to effectively cure the majority of diseases that humans suffer from today. Nanotechnology has the potential to become a core technology not only for modern medicine and dentistry, but also for other fields such as chemistry, physics and engineering (Patil et al). Once scientists determine a system that eliminates the dangers of nanoscale materials and regenerative medicine, nanotechnology will undoubtedly become the foundational technology of modern medicine. Medical developments in nanotechnology have multiple uses and could potentially save thousands of lives. Nanomedicine is an emerging field that “involves the maintenance of cells, tissues, and organs by applying cell therapy and tissue engineering methods” (Patil et al). This often includes not only the use of a variety of materials at the nanoscale, but also the rewriting or replacement of DNA sequences in cells (Patil et al). These procedures are mainly carried out by researchers involved in drug discovery as well as doctors in the middle of the article ......hnologies, August 11, 2006. Web.
