The study, published in the journal Nature Nanotechnology, describes how researchers at the University of California, Berkeley, used DNA origami to create a series of tiny structures that can change their shape when exposed to different chemicals.
The structures, which are about 10,000 times smaller than a human hair, are made from DNA strands that are folded into specific shapes. When the DNA strands are exposed to certain chemicals, they can unfold and refold into different shapes.
This allows the researchers to create structures that can move and dance in a variety of ways. For example, one structure can fold and unfold into a helix shape, while another can fold and unfold into a cube shape.
The researchers believe that these self-assembled DNA nanostructures could be used to create new types of materials and devices. For example, they could be used to create sensors that can detect specific chemicals, or they could be used to create actuators that can move in response to a stimulus.
The study is a major advance in the field of DNA origami, which is a rapidly growing field that has the potential to revolutionize the way we create materials and devices.
