In this century, health care industries are mainly focusing on the development of minimally invasive techniques for diagnosing as well as for curing ailments. For the implant of bones and membranes, a better-advanced technology is needed. As an advancement, scientists incorporated robots at the nanoscale to enhance the developments in the medical field. Nanorobotics is a growing area of nanotechnology in which they collaborate with machines or robots which is at the nanoscale. There are many challenges for the growth of this technology, not only from the technical side but also from the introduction of new material into the human body and environment. On the other side, the advantages of nanobots are immense. Nanobots can pave way for many creative approaches especially as good applicants for complex treatments. The goal of this paper is to peek into the applications of nanobots in medicine.
