Abstract
Nanorobots are the nano devices that are used for protecting or treatment against pathogens in humans. The use of nanorobots technology has become familiar and increasingly common, especially with pharmaceutical technology. We conducted this research paper by observing the different types of reviews, as well as conducting and evaluating literature review papers. This research is provided detailed overview of the types, properties and application of nanorobot in the diagnosis, prevention and treatment of various diseases. Nanorobots technology is rapidly emerging in the medical field, and this subfield has been termed nanomedicine. Nanorobotics are developing wide potential applications across all fields of medicine, and expanding the number of therapeutic options available, while also improving the efficacy of existing treatments. The most recent applications of these devices include targeted drug delivery to the brain, glucose monitoring in patients with diabetes, bone reconstruction, cancer treatment, blood clot removal, nerve regeneration and protein peptide based drug delivery systems.
