  2. Molecular motor - Wikipedia

    en.wikipedia.org/wiki/Molecular_motor

    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 ...

  3. Synthetic molecular motor - Wikipedia

    en.wikipedia.org/wiki/Synthetic_molecular_motor

    The prototype of a chemically driven rotary molecular motor by Kelly and co-workers. The motor by Kelly and co-workers is an elegant example of how chemical energy can be used to induce controlled, unidirectional rotational motion, a process which resembles the consumption of ATP in organisms in order to fuel numerous processes. However, it ...

  4. Molecular machine - Wikipedia

    en.wikipedia.org/wiki/Molecular_machine

    The first example of an artificial molecular machine (a switchable molecular shuttle). The positively charged ring (blue) is initially positioned over the benzidine unit (green), but shifts to the biphenol unit (red) when the benzidine gets protonated (purple) as a result of electrochemical oxidation or lowering of the pH .

  5. Motor protein - Wikipedia

    en.wikipedia.org/wiki/Motor_protein

    Many of these molecular motors are ubiquitous in both prokaryotic and eukaryotic cells, although some, such as those involved with cytoskeletal elements or chromatin, are unique to eukaryotes. The motor protein prestin, [14] expressed in mammalian cochlear outer hair cells, produces mechanical amplification in the cochlea. It is a direct ...

  7. Brownian motor - Wikipedia

    en.wikipedia.org/wiki/Brownian_motor

    Brownian motors are nanoscale or molecular machines that use chemical reactions to generate directed motion in space. [1] The theory behind Brownian motors relies on the phenomenon of Brownian motion, random motion of particles suspended in a fluid (a liquid or a gas) resulting from their collision with the fast-moving molecules in the fluid. [2]

  8. Micromotor - Wikipedia

    en.wikipedia.org/wiki/Micromotor

    Easily the most important examples are biological motors such as bacteria and any other self-propelled cells. Synthetically, researchers have exploited oxidation-reduction reactions to produce chemical gradients, local fluid flows, or streams of bubbles that then propel these micromotors through chemical media. [ 2 ]

  9. Single-molecule electric motor - Wikipedia

    en.wikipedia.org/wiki/Single-molecule_electric_motor

    The single-molecule electric motor can be efficiently used in engineering, [2] nanotechnological applications and medicinal applications, [3] where drugs could be delivered to specified locations more accurately. [3] By altering the chemical structure of the molecule, it could become a component of a nanoelectromechanical system (NEMS). It also ...
