Self-Replicating Robots Made From DNA We’re Created
Scientists at New York University in the US and Ningbo University in China have created tiny robots made from DNA that can reproduce themselves. The results of the study were published in the journal Science Robotics.
To reproduce the technical process, a certain temperature and ultraviolet radiation of a given intensity are required. Nanorobots consisting of DNA chains catch four specified DNA fragments from the environment and bend them to obtain the required spatial figure, after which ultraviolet light “welds” the fragments at the points of contact. Then the nanorobot releases the finished structure and begins assembling the next one exactly the same. Likewise, it can create a copy of itself given the necessary DNA strands, which will then engage in production or self-replication.
According to the researchers, the scientific work paves the way for the production of nanoscale industrial robots that are capable of automatically performing cycles of the same tasks for processing and producing nanomaterials with constant accuracy. In addition, such nanorobots could be used to search for and destroy cancer cells in the human bloodstream without the need for surgery, or to recycle trash in the ocean.
