According to the University of Manchester's official website on September 20th, the school's scientists developed the world's first "molecular robot", which can receive chemical instructions and complete the basic tasks of assembling molecules, and can be used to develop drugs, design advanced manufacturing processes and build in the future. Molecular assembly lines and molecular factories.
David Ray, a professor at the University of Manchester's School of Chemistry, published a paper in the journal Nature. The total number of atoms of carbon, hydrogen, oxygen and nitrogen that make up a molecular robot is only 150, and the size is only a millionth of a millimeter. Tens of billions of such robots are piled up, and they are only as big as a salt. But such a tiny molecular robot has a robotic arm that can manipulate individual molecules according to instructions and build molecular products with robotic arms.
Although the construction of such molecular robots is extremely complex, the techniques used by Ray's team are based on simple chemical reactions, all of which are atomic and molecular interactions, and how small molecules build chemistry such as macromolecules. Lei explained that all matter is made up of molecules, and the basic unit of the molecule is atomic, which is very similar to the process of forming a Lego robot, but this time it is replaced by an atom, which is the same as the synthesis process of drugs and plastic products.
The instructions it accepts are chemical reactions carried out in a specific solution. Scientists can issue different chemical commands to the molecular robot by operating and programming different chemical reactions. The robot responds to these instructions and performs some basic tasks. “Once the molecular robots are synthesized, scientists will give them chemical instructions through chemical reactions, just like computer programs tell them when and what tasks to perform.â€
Similar to robotic assembly of automotive body components on automotive assembly lines, molecular robots can install and immobilize molecular components in different ways to create different molecular products. And because of their small size, these molecular robots have many advantages, which can reduce material requirements, accelerate drug development, significantly reduce energy consumption, and promote product miniaturization. Therefore, it is expected to bring exciting applications in many fields in the future.

The charm of science and technology exists in the persistence of the hypothesis model, which appears in the surprise of “seeing†the unknown world through various tools, and also in creating unknown pleasures with known conditions. The achievements of this article are obviously in the last case. Scientists regard the basic law as a magic wand and chanting a spell, and the molecules are obedient.
