The ideal material for interfacing electronics with living tissue is soft, stretchable, and just as water-loving as the tissue itself--in short, a hydrogel. Semiconductors, the key materials for ...

Growing cells in the laboratory is an art that humans have mastered decades ago. Recreating entire three-dimensional tissues is much more challenging. Researchers are developing a new hydrogel-based ...

A DNA hydrogel engineered from tetrahedral nanostructures accelerates burn wound healing by directing immune cell behavior, reducing inflammation, and supporting tissue regeneration through structural ...
