Chemists at the University of Groningen have designed a near-infrared light-powered rotary motor, the type that can be used to deliver autonomous motion to a system, or to ensure that a system responds to a prompt on command. The chemists administered near-infrared light to their molecular motor through an antenna.
Many biological applications require low-energy, low-intensity light to power a molecular motor and effectively penetrate tissue. UV light, effective at making molecular motors operational, can be harmful to sensitive surrounding materials. University of Groningen professor of organic chemistry Ben Feringa designed and introduced a light-driven, unidirectional rotary molecular motor in 1999, and, 17 years later, he…READ MORE
