A new study has been published showcasing a new DNA-based nanobot that could open the door to producing life-saving drugs in the human body. A team of researchers from New York University have developed DNA-based nanobots that could, in theory, replicate themselves exponentially. Developed by Feng Zhou and his team, the tiny DNA bots consist of only four DNA strands and can copy themselves one at a time using their structure as a template. These DNA nanobots could open up exciting opportunities to produce life-saving drugs inside your body.

The nanobots are created with four DNA strands and measure around 100 nanometers. To put that into perspective, you could line up about a thousand of them to fit the width of a human hair, give or take. They are also held in a solution with specific DNA-strand raw materials needed for them to work.
