Abstract— Nanorobot,an applications of nanotechnology. Nano-robots also shows an necessary part incritical care submission in medicine and health. Its superior role as asubstitute to conventional medical care is investigated, as well as its absenceof side effects while effecting the cure. This work evaluates the potential ofinorganic and organic nanobots for their diagnostic, and therapeutic role ofunder different critical care condition with examples. Nanorobotics is anemerging field of nanotechnology which deals with design and construction ofdevices at an atomic, molecules or cellular level. These hypotheticalnanorobots will be extremely small and would transverse inside the human blood.As these nanorobots would have special sensors to detect the target molecules,it can be programmed to diagnosis and treat fatal diseases. Application ofnanorobots in the treatment of cancer is one of the fascinating fields ofresearch.
Keywords: Nanorobot, diagnostic, critical care.
