American scientists use DNA fragments to create nanobots
The American team of scientists created an unusual nano-scale "robot." This robot is assembled from DNA fragments. It has a "body" and two "legs." This innovative structure can "walk" autonomously on the surface of uneven cells.
Experts from the University of Texas at Austin posted research results on NatureNanotechnology magazine.
Previously occurring molecules of a similar type can only move in a predetermined direction; the results of a newly developed scientist can "go" 36 steps, and can independently determine the direction in which it is going. Until it encounters obstacles, it will require the help of experimenters.
This tiny "walker" is created on the basis of a single strand of DNA. It will be linked to the other two genetic code parts. They can attach to cells with special surface chemistry.
According to a study of authors, this is a small step towards creating a “DNA robot†that can act independently in the human body, but it is also a very important step.
Scientists recommend treating their inventions as "nano-doctors" who can move inside the human body and can "walk around" between cells and find cancer and other problematic areas before reporting these potential risks to humans. . After the internal mechanisms of DNA robots are perfected, they will be able to eliminate harmful cells on their own.
"All great discoveries begin with a small attempt," the scientist said. It is these tiny attempts that have led us to create "walking villains" that are assembled from DNA molecules.
