WebThat molecule was developed into a “ nanocar ,” whose four wheels rotate to move the microscopic structure forward along a plane, like a minuscule car with four-wheel drive. Feringa also showed that the molecule could be used to rotate a glass rod thousands of times larger than the motor itself. Classification of Molecular machines: WebL Feringa “for the design and synthesis of molecular machines”'. Quote from the Nobel Prize website. Molecular machines are a fascinating group of molecules developed over the past few decades. A 'major breakthrough' cited was by Sauvage and co-workers in 1983.
