Spinning strands : A hydrogel fiber made entirely of DNA without any covalent cross‐links, composed of intertwined toroid entanglements of flexible DNA strands (see scheme), was prepared by a one‐step wet‐spinning method with a hydrophilic ionic liquid as the condensing agent and coagulation solvent. The internal structure of the fiber was a disordered arrangement of strands with a B‐DNA form. The fiber was also stable in various aqueous solutions.
