Synthetic molecular motors and mechanical machines.
The widespread use of controlled molecular-level motion in key natural processes suggests that great rewards could come from bridging the gap between the present generation of synthetic molecular systems, which by and large rely upon electronic and chemical effects to carry out their functions, and the machines of the macroscopic world, which utilize the synchronized movements of smaller parts ...
متن کاملMolecular Motors , Actuators , and Mechanical Devices
Atomically precise manufacturing systems, such as those described in Nanosystems [1], will utilize molecular motors and actuators that drive components to perform useful work. The conversion of electrical and chemical energy into mechanical motion is facilitated by the use of gears, bearings, drive shafts, springs, and so forth, to direct the motion of components and minimize energy losses. Thu...
متن کاملMolecular , Supra molecular , and Macromolecular Motors and Artificial Muscles
Recent developments in chemical synthesis, nanoscale assembly, and molecularscale measurements enable the extension of the concept of macroscopic machines to the molecular and supramolecular levels. Molecular machines are capable of performing mechanical movements in response to external stimuli. They offer the potential to couple electrical or other forms of energy to mechanical action at the ...
متن کاملMechanical Properties of Organelles Driven by Microtubule-Dependent Molecular Motors in Living Cells
The organization of the cytoplasm is regulated by molecular motors which transport organelles and other cargoes along cytoskeleton tracks. Melanophores have pigment organelles or melanosomes that move along microtubules toward their minus and plus end by the action of cytoplasmic dynein and kinesin-2, respectively. In this work, we used single particle tracking to characterize the mechanical pr...
متن کاملA mechanical actuator driven electrochemically by artificial molecular muscles.
A microcantilever, coated with a monolayer of redox-controllable, bistable [3]rotaxane molecules (artificial molecular muscles), undergoes reversible deflections when subjected to alternating oxidizing and reducing electrochemical potentials. The microcantilever devices were prepared by precoating one surface with a gold film and allowing the palindromic [3]rotaxane molecules to adsorb selectiv...
