A nucleic acid robot (nubot) is an organic molecular machine at the nanoscale. [46] DNA structure can provide means to assemble 2D and 3D nanomechanical devices. DNA based machines can be activated using small molecules, proteins and other molecules of DNA.
Molecular machines differ from other stimuli-responsive compounds that can produce motion (such as cis-trans isomers) in their relatively larger amplitude of movement (potentially due to chemical reactions) and the presence of a clear external stimulus to regulate the movements (as compared to random thermal motion).

I and Vol. IIA by Robert Freitas and Kinematic Self-Replicating Machines "KSRM Table of Contents Page". Molecularassembler.com by Robert Freitas and Ralph Merkle. Nanotechnology: Molecular Speculations on Global Abundance Edited by BC Crandall (ISBN 0-262-53137-2) offers interesting ideas for MNT applications.
These include hypothetical machines that manipulate individual atoms and machines with organism-like self-replicating abilities, mobility, ability to consume food, and so forth. These are quite different from devices that merely (as defined above) "guide chemical reactions by positioning reactive molecules with atomic precision".
Nanomanufacturing refers to manufacturing processes of objects or material with dimensions between one and one hundred nanometers. [15] These processes results in nanotechnology, extremely small devices, structures, features, and systems that have applications in organic chemistry, molecular biology, aerospace engineering, physics, and beyond.

Nanomedicine is the medical application of nanotechnology. [1] Nanomedicine ranges from the medical applications of nanomaterials and biological devices, to nanoelectronic biosensors, and even possible future applications of molecular nanotechnology such as biological machines.
Artificial intelligence is coming for your job: 41% of employers intend to downsize their workforce as AI automates certain tasks, a World Economic Forum survey showed Wednesday.
