Nano-robots and applications, a review

Nano-bots or Nano-robots are nanoscale devices that may enter the body's cells and execute a specific purpose. They can be manmade or organic. Nanotechnology is presently used in a variety of medical applications, such as medication delivery systems, as well as in a variety of other items, such as sunscreens, meals, and cosmetics. Nano-robot research is critical because, if successful, it could revolutionize the treatment of chronic diseases like cancer, or it could be used to treat damaged organs without surgery. The equivalent of ten atoms in size. Despite the encouraging outcomes of Nano-robots, scientists have a significant challenge in producing such small devices.
