Abstract: DNA, long known as the carrier of genetic information, has become an important material in the field of soft matter, used to create diverse nanostructures. Our research focuses on DNA hydrogels, which have promising biomedical and environmental applications. These hydrogels are built from nanostars, which are formed from short DNA sequences with sticky-ends. At low temperatures, these nanostars self-assemble into a 3D network, creating the DNA hydrogel. We study the underlying physics of these hydrogels using a multi-technical approach, over multiple scales, from nanoscale to macroscale. Our results show that changing the design of the nanostar, even slightly, changes the thermodynamic and rheological properties of the resulting DNA hydrogel. We think that our study will contribute significantly to design functional gels with precise properties for diverse applications in the future.
