Scientists at the University of Texas at Austin created a robot made of deoxyribonucleic acid (the fancy way of saying DNA). I’m not really sure how, but the tiny machine was designed to walk in non-programmed paths across surfaces in any direction (they can walk anywhere they want).
The “DNA walkers” are made from a single DNA cell with legs and a torso, and walk by putting one leg in front of the other. This is both really cool and really odd. I’m not sure at all sure how it works.
In any case, the scientists are hoping they can send these into a human body and have them “tag” cancer cells for imaging or otherwise. To me, it seems like the DNA walkers could carry little bottles of something that kills cancer cells and if they found one, dump the stuff on it 😀
The invention is truly amazing.
