Now, a team at the University of Manchester in the UK has reached another milestone. They’ve developed a robot so small, it operates on the molecular level. This, the world’s first molecular robot has an arm which can manipulate individual molecules or move them in clusters.
The thing is a millionth of a millimeter in size. To give you an idea of the scale we’re talking about, one quintillion (a billion billion) of them piled together would be about equal to a few grains of salt. Each machine is comprised of 150 atoms. That includes carbon, hydrogen, oxygen, and nitrogen atoms. Though small, these machines could offer us incredible capabilities, such as to work in tiny, molecular factories, in order to manufacture the next generation of materials and products.
To put that into even better perspective, that's a nanometer in size. I mean, Christ! Just say it!
