Approaches to rotary molecular motors*

Interest has recently intensified in the search for molecular motors and actuators capable of delivering useful work to nanodevices under the control of electrochemical or photochemical power sources. While many of these man-made molecular machines are designed to deliver rectilinear motion, very few are proposed for the controlled delivery of rotary motion on the time scale characteristic of i...

Unidirectional rotary motion in achiral molecular motors.

Control of the direction of motion is an essential feature of biological rotary motors and results from the intrinsic chirality of the amino acids from which the motors are made. In synthetic autonomous light-driven rotary motors, point chirality is transferred to helical chirality, and this governs their unidirectional rotation. However, achieving directional rotary motion in an achiral molecu...

A redesign of light-driven rotary molecular motors.

Structural modification of unidirectional light-driven rotary molecular motors in which the naphthalene moieties are exchanged for substituted phenyl moieties are reported. This redesign provides an additional tool to control the speed of the motors, and should enable the design and synthesis of more complex systems.

Novel Rotary Inchworm Motors

In this paper, we will demonstrate a family of novel Rotary Inchworm motors using four gap-closing actuators (GCA). Design issues, fabrication process, and expected operation of several rotary motors will be described. The motor is to be batch fabricated using Seth Holler’s Silicon-on-Insulator (SOI) plus hinges process. An output torque of the order of nN-m with a torque density in the range o...

Rotary protein motors.

Three protein motors have been unambiguously identified as rotary engines: the bacterial flagellar motor and the two motors that constitute ATP synthase (F(0)F(1) ATPase). Of these, the bacterial flagellar motor and F(0) motors derive their energy from a transmembrane ion-motive force, whereas the F(1) motor is driven by ATP hydrolysis. Here, we review the current understanding of how these pro...
