A future nanocar with a synthetic molecular motor has been developed by Jean-Francois Morin et al. [15] It is fitted with carborane wheels and a light-powered helicene synthetic molecular motor. Although the motor moiety displayed unidirectional rotation in solution, light-driven motion on a surface has yet to be observed.
A proposed branch of research is the integration of molecular motor proteins found in living cells into molecular motors implanted in artificial devices. Such a motor protein would be able to move a "cargo" within that device, via protein dynamics , similarly to how kinesin moves various molecules along tracks of microtubules inside cells.
Synthetic molecular motors are molecular machines capable of continuous directional rotation under an energy input. [2] Although the term "molecular motor" has traditionally referred to a naturally occurring protein that induces motion (via protein dynamics), some groups also use the term when referring to non-biological, non-peptide synthetic motors.
The helicity of a particle is positive (" right-handed") if the direction of its spin is the same as the direction of its motion and negative ("left-handed") if opposite. Helicity is conserved. [1] That is, the helicity commutes with the Hamiltonian, and thus, in the absence of external forces, is time-invariant. It is also rotationally ...
Molecular Devices supplies analytical systems, including instruments, software, and reagents, to accelerate and improve drug discovery and basic life science research. Molecular Devices is based in Silicon Valley, CA, United States, and has regional offices in the United Kingdom, Germany, Austria, Korea, China, and Japan to support the global ...
Molecular motors are natural (biological) or artificial molecular machines that are the essential agents of movement in living organisms. In general terms, a motor is a device that consumes energy in one form and converts it into motion or mechanical work ; for example, many protein -based molecular motors harness the chemical free energy ...
HRL Laboratories (formerly Hughes Research Laboratories) is a research center in Malibu, California, established in 1960. Formerly the research arm of Hughes Aircraft, it is currently owned by General Motors Corporation and Boeing. It is housed in two large, white multi-story buildings overlooking the Pacific Ocean.
Unlike a molecular motor, any mechanical work done due to the motion in a switch is generally undone once the molecule returns to its original state unless it is part of a larger motor-like system. The image on the right shows a hydrazone -based switch that switches in response to pH changes.
