Molecular machines and motors

Molecular motors, also called molecular machines, are either natural or synthetic molecules that convert chemical energy into mechanical forces and motion. An example of a biological motor is the protein kinesin, which uses the hydrolysis of adenosine triphosphate to move along microtubule filaments.

    FoF1-ATPase is a vital molecular machine in organisms responsible for the catalytic synthesis of the basic energy unit ATP. In this Review, the development of FoF1-ATPase reconstitution into artificial architectures is discussed ultimately leading to the development of stimuli-responsive ATP synthesis.

    One-dimensional diffusive binding represents an important mechanism used by nature to facilitate many fundamental biochemical processes. Now, a completely synthetic system with similar capabilities has been constructed. The system was exploited to significantly speed up bimolecular reactions and to catalytically transport molecular cargo in solution and within physically separated compartments.

    Biological motors which convert energy into mechanical work inspire the fabrication of synthetic motors. Here the authors demonstrate self-assembled colloidal motors which are driven to a range of responses controlled by the feedback between light polarization and deformation of a liquid crystal.

    Micromotors have a range of potential healthcare applications. Here, the authors describe the development of a metal nanoparticle DNA micromotor which can be used to detect human HIV-1 by a change in the motion of the micromotors, monitored by cell phone camera, triggered by binding of HIV-1 RNA.
