Scientists create molecular robot capable of building other molecules
We have seen robots that can inspect bridges for faults, offer religious blessings and even weed the garden. Now, scientists at England’s University of Manchester have created a robot the size of a molecule that is capable of building other molecules. The robots are made up of 150 atoms each and measure just a millionth of a millimeter – it would take a billion billion of them to equal the size of a grain of sand. Yet, they can be programmed to move and build molecular cargo. Unlike their larger cousins, which are operated by computer programs, the molecular robots are constructed and operated using chemical processes. Using special solutions, the robots can be ‘programmed’ to carry out different chemical reactions allowing the building of different molecules.
