Nanotechnology - Application In Oral Cancer-Nanotechnology provides innovative tools for the diagnosis of oral cancer. They aid in analysing the parameters such as cellular mechanics, morphology and cytoskeleton which is difficult to achieve using the conventional technology. Nanotechnology has the potential tool to detect cancer cells, diagnose and deliver specific targeted anti-cancer therapeutic drugs. Recent advances in the field of nanotechnology have provided a great hope for the patients affected by oral cancer. In the future nanomedicine will change the dentistry, healthcare and human life more effectively than any other inventions.
