Nanorobots Recent and Future Advances in Cancer or Dentistry Therapy- A Review

Nanorobots are considered to be the next generation of Nanomachine which deals with design and construction of devices at an atomic, molecules or cellular level. These hypothetical Nanorobots will be extremely small and would transverse inside the human blood. In 2015 there were 11,48,692 cases of cancer in India. The present methods for the treatment of cancer are not that effective as 99% of chemotherapy drugs do not reach the cancer cells. However, Nanorobots which are roughly 100 times smaller than human tissues could do this and hence creates a huge area for exploration in the field of biomedical research. As scientists predict in coming years cancer will be a chronic but manageable disease. Especially in the treatment of cancer, Cerebral Aneurysm, kidney stones removal, also to remove the defected part in our DNA structure and some other treatments that have the greatest aid to save human lives. This paper guides to the recent research on Nanorobots in the biomedical applications. Treatment possibilities might include the application of nanotechnology to local anesthesia, dentition denaturalization, the permanent cure for hypersensitivity, complete orthodontic realignment in a single visit, covalently bonded diamondized enamel, and continuous oral health maintenance using mechanical dentifrobots. Nanorobots can offer a number of advantages in drug delivery over present methods. In addition, the current study also involves the future aspects of Nanorobots.
