Caltech scientists use DNA tiles to play tic-tac-toe at the nanoscale
Courtesy Qian Lab/Caltech. Scientists at Caltech have created the world’s smallest game board for playing tic-tac-toe out of DNA strands. What’s more, it’s possible to swap hundreds of DNA strands in and out at once to reconfigure the nanostructure at will, making it possible in principle to build complicated nanomachines in different custom patterns. The …
