Nanorobot

Nanorobots have the ability to create infinite copies of themselves. Researchers have developed a programmable nanorobot composed of just four strands of DNA. This tiny robot captures other DNA fragments using ultraviolet light and connects them together to create new nanomachines, including its own replicas. A thousand such bots can fit on the width of a human hair. This technology can be applied in the production of medications, enzymes, and other chemical substances inside the cells of organisms. However, some believe that self-replicating nanorobots have the potential to cause an apocalypse.
