From the Clarendon Laboratory, Department of Physics at the University of Oxford in England comes a programmable DNA robot.
The robot is made up of sub-microscopic synthetic DNA and moves along tracks separated by only 6nm (nanometers).
The robot can be programmed using something called a “fuel hairpin”. This is a molecule that acts as a fuel cell and also carries instructions on which way the robot should go, allowing it to go right or left when it comes to a junction. Hopefully in the future this would allow doctors to precisely target where drugs should end up in a patients body.
The research was done by Andrew Turbefield, a professor at Oxford, along with other colleagues.
