DNA nanotechnology leverages the programmability of DNA molecules for constructing nanostructures and molecular computers. Recent advancements highlight that sequence-designed DNA can undergo phase separation, introducing a novel dimension to this field. This phenomenon enables the design of dynamic DNA droplets through liquid-liquid phase separation, dependent on base sequences. The sequence dependency further extends to tuning the droplets’ physical properties and constructing DNA droplet computers. Additionally, phase separation occurring on a two-dimensional closed interface results in compartmental capsules. The cover image illustrates the characteristics of DNA phase separation.
