Johns Hopkins engineers have developed gel strips that change shape when given chemical instructions written in DNA code. These “gel automata,” measuring just centimeters, can grow or shrink, transforming from one letter or number to another when triggered by specific DNA molecules. This breakthrough opens possibilities for shape-shifting robots and medical devices that can reconfigure themselves to perform various tasks. Their research is published in Nature Communications.
