DNA nanobot can deliver medicine in the human bloodstream

Scientists have built and tested a walking robot that can pick up and carry objects but is too small to be seen with the naked eye. The machine is made from DNA, the molecule that carries the'book of life' genetic instructions for all living things. In future, similar nanobots could be used to assemble new chemicals and materials at the molecular level, build incredibly miniaturised circuit boards, or roam through blood vessels delivering medicines. Shown here is a conceptual illustration of a DNA robot sorting two types of cargos. The machine is made from DNA, the molecule that carries the'book of life' genetic instructions for all living things Nanobots are devices made from DNA that are so small they can be injected into the human bloodstream. The nanobot described in the journal was made with a few nucleotides, sub-unit elements of DNA.
