Small is IN:Single molecule is tiniest electric motor ever

There has been a remarkable advancement in performing Molecular arrangements which pave way for useful NanoElectronics in the Future. Here is what we came across recently:

The smallest motor ever made and that's why its contesting in the Guinness World Records.
Molecules have previously converted energy from light and chemical reactions into directed motion like rolling or flapping. Electricity has also set an oxygen molecule spinning randomly. But controlled, electrically-driven motion – necessary for a device to be classed as a motor – had not yet been observed in a single molecule.
To address this, E. Charles Sykes at Tufts University in Boston and colleagues turned to asymmetric butyl methyl sulphide, a sulphur atom with a chain of four carbons on one side and a lone carbon atom on the other. They anchored the molecule to a copper surface via the sulphur atom, producing a lopsided, horizontal "propeller" that is free to rotate about the vertical copper-sulphur bond
