(109 meters) is called nanorobotics [ 2—4] that refers to the nanotechnology engineering discipline of designing and building nanorobots. <...> A nanorobot can be defined as a molecular machine consisting of a group of distinct molecular combinations. <...> Nanomachines are largely in the research-and-development phase [ 5 ], but some primitive molecular machines and nanomotors have been tested. <...> The first useful applications The field creating robots or machines <...>
