A nanomotor is a molecular or nanoscale device capable of converting energy into movement. It can typically generate forces on the order of piconewtons. [1] [2] [3] [4]
The first nanomotor can be thought of as a scaled down version of a comparable microelectromechanical systems (MEMS) motor. The nanoactuator consists of a gold plate rotor, rotating about the axis of a multi-walled nanotube (MWNT). The ends of the MWNT rest on a SiO 2 layer which form the two electrodes at the contact points. Three fixed stator ...
A nanoscale plasmonic motor (sometimes called a "light mill" [1]) is a type of nanomotor, converting light energy to rotational motion at nanoscale.It is constructed from pieces of gold sheet in a gammadion shape, embedded within layers of silica.
The term is often used interchangeably with "nanomotor," despite the implicit size difference. These micromotors actually propel themselves in a specific direction autonomously when placed in a chemical solution. There are many different micromotor types operating under a host of mechanisms.
As noted by Richard Feynman in his famous talk in 1959, "There's Plenty of Room at the Bottom," there are many potential applications of machines at smaller and smaller sizes; by building and controlling devices at smaller scales, all technology benefits.
Application of nanomotor implants have been proposed to achieve thorough disinfection of the dentine. [21] [22] In vivo imaging is also a key part in nanomedicine, as nanoparticles can be used as contrast agents for common imaging techniques such as computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography ...
A ribosome is a biological machine that utilizes protein dynamics. Molecular motors are natural (biological) or artificial molecular machines that are the essential agents of movement in living organisms.
Scheme of an adiabatic quantum motor made of a quantum dot coupled to a rotating wheel. An adiabatic quantum motor is a mechanical device, typically nanometric, driven by a flux of quantum particles and able to perform cyclic motions.
