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.
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 ...
Non-invasive micro-test technology (NMT) is a scientific research technology used for measuring physiological events of intact biological samples. NMT is used for research in many biological areas such as gene function , plant physiology , biomedical research , and environmental science .
Variations in the electrical conductivity and magnetic permeability of the test object, and the presence of defects causes a change in eddy current and a corresponding change in phase and amplitude that can be detected by measuring the impedance changes in the coil, which is a telltale sign of the presence of defects.

An electrostatic motor is based on the attraction and repulsion of electric charge. Usually, electrostatic motors are the dual of conventional coil-based motors. They typically require a high voltage power supply, although very small motors employ lower voltages.
