Why you go for nanorobotics from robotics?

Answer 1

Nanorobotics is the technology of creating machines or robots at or close to the microscopic scale of a nanometer.

Nanorobotic devices will be a boon to the biomedical research, therapeutics, and diagnostics arenas, as these devices offer the promise to manipulate single cells, to deliver small amounts of material at precise locations, to detect target agents even at a low nanomolar concentrations level and, in general, to do useful physical work on the molecular level. Such bionanorobotic devices will hopefully be the basis of an arsenal of future medical and nanotech devices that will automatically perform operations, inspections and treatments while achieving ultra-high accuracy in time and space.
