The benefits of miniaturizing machinery are plenty. Apart from the obvious cost advantages since the material and power requirements are greatly reduced, the potential applications of miniature machinery are many. Therefore, when researchers developed a molecular robot that performs basic tasks, it\u2019s definitely a win for science.<\/p>\n
The molecular robots constructed by scientists are so tiny that if a billion of these were piled on top of each other, they would still be the size of a single grain of salt. The robots are a millionth of a millimeter in size and each of them are capable of manipulating a single molecule. They can be programmed to move and build molecules by using a tiny robotic arm. Each individual robot is made up of just 150 carbon, hydrogen, oxygen, and nitrogen atoms. Chemical reactions are carried out in special solutions by the robots.<\/p>\n
