“Topologically tunable” DNA-based material has potential applications in drug delivery, tissue regeneration

DNA is usually idealized as the “molecule of life,” but it is also a highly advanced polymer that can be used for cutting-edge materials. Apart from storing information, other interesting aspects of DNA are its topological and geometrical properties, like super-coiling and knotting.
