Nanorobots made of DNA origami demonstrated computing capacities and completed pre-programmed task inside the living organism was reported by a team of bioengineers at Wyss Institute at Harvard University and Institute of Nanotechnology and Advanced Materials at Bar-Ilan University. As a proof of concept, the team injected various kinds of nanobots (the curled DNA encasing molecules with fluorescent markers) into live cockroaches. By tracking the markers inside the cockroaches, the team found the accuracy of delivery of the molecules (released by the uncurled DNA) in target cells, the interactions among the nanobots and the control are equivalent to a computer system. The complexity of the logic operations, the decisions and actions, increases with the increased number of nanobots. The team estimated that the computing power in the cockroach can be scaled up to that of an 8-bit computer.
