Smallest Molecular Gear

Nanotechnology is that technology that cannot be seen.I mean't cannot be seen with our naked eye.Scientists have understood the uses of nanotechnology and gears are the things which can make a highway for the Nano-machines.
Scientists made 1.2nm(nano meters) small nano gear and this would be too big with the ones compared to the gears which are going to be built in the future.

Nano-Gears of size in the scale of nano-maters.

Making the gear of the size of few atoms is not a big achievement but one should be able to have control over the rotation and several other physical properties of such kind and this would be an amazing thing.This is exactly what has made Professor Christian Joachim popular in the world of Nanotechnology and Nano machines.
He said that "the team at the IMRE(Institute of Materials and Research Engineering) has invented a working and controllable nano-gear which is going to make way for more machines which are no more than the size of a grain of sand".
