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: WebWhereas biology has perfected its machines over billions of years of evolution, chemists keen to imitate these structures are just getting started. In the late 1980s, researchers started building assemblies of molecules that contain mechanically interlocked components, where two or more parts can’t be separated without breaking a covalent bond.
