Can you list the top facts and stats about Synthetic molecular motor?
Summarize this article for a 10 year old
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. Many chemists are pursuing the synthesis of such molecular motors.
The basic requirements for a synthetic motor are repetitive 360° motion, the consumption of energy and unidirectional rotation.[citation needed] The first two efforts in this direction, the chemically driven motor by Dr. T. Ross Kelly of Boston College with co-workers and the light-driven motor by Ben Feringa and co-workers, were published in 1999 in the same issue of Nature.
As of 2020, the smallest atomically precise molecular machine has a rotor that consists of four atoms.[3]
