Scientists create microscopic DNA 'flower robots' that can deliver drugs, heal wounds and even clean the planet. Scientists have created microscopic “soft robots” shaped like flowers that can change their shape and behaviour. Researchers at the University of North Carolina built these “DNA flowers,” tiny machines made from DNA and inorganic materials. These flowers can fold and unfold in seconds, making them one of the most dynamic materials ever engineered. The DNA inside each flower acts like a mini computer program, directing how it moves and reacts to its surroundings. When environmental conditions change, the petals can open, close, or trigger chemical reactions. This technology could one day perform tasks inside the body, like delivering drugs or removing clots. Researchers drew inspiration from nature’s designs, like blooming flowers and growing tissue, to create these synthetic materials. In the future, these DNA flowers could revolutionise medicine, environmental cleanup, and data storage.
