n. A microscopic motor
Wikipedia
Micromotors are very small particles (measured in microns) that can move themselves. These micromotors actually propel themselves in a specific direction autonomously when placed in a chemical solution. A set of oxidation-reduction reactions produce a stream of bubbles that then propels these micromotors through the chemical media. Spherical micromotors are called Janus spheres, because they are composed of two different materials, like the two-faced Roman god of change Janus.
Micrometers may have applications in medicine since they have been shown to be able to deliver materials to living cells within an organism. They also have been shown to be effective in degrading certain chemical and biological warfare agents.
