Nanomachines wind and unwind polymers
Combining two types of light-activated molecular machines, chemists in France have created a system that winds and unwinds polymer chains, resulting in a material that contracts and expands, depending upon the wavelength of light that shines upon it. The system, developed by the University of Strasbourg’s Nicolas Giuseppone and coworkers, could lead to new types of actuators and artificial muscles.
A couple years ago, Giuseppone’s group tethered light-activated motor molecules to polymer . . .
